Application Compatibility Issues

    General discussion

  • The mitigations offered by EMET have the potential to break some applications.  This thread is to discuss people's experiences with applications that do not work correctly under EMET.  The goal is to isolate which specific mitigations cause problems and for which applications (or plug-ins where appropriate).  For those trying to determine which mitigations are causing problems, the most likely candidates are EAF and DEP.

    Here are the issues the EMET support team has been able to confirm:

    Application or plug-in

    Issues that occur

    Mitigation or setting causing the issues


    Fails to run


    NetFlix SilverLight app

    Video playback in browser fails


    ATI Drivers

    System blue screens on boot

    System ASLR policy set to always on

    (must enable unsafe settings to see this option)

    iPod Synchronization service

    Service crashes

    System DEP policy set to always on


    System gives “out of memory” error messages

    System DEP policy set to always on

    If you have experienced application compatibility problems with EMET, please share your experiences on this thread.  The more detail you can provide about what the issues are and what

  • You can also add UltraISO,, which does not like mandatory DEP. All other protections can be enabled and it works fine, though.

  • When EMET's protections are enabled for web browsers and user installs or upgrades to latest version of Trusteer Rapport (protection from phishing, keylogging and financial malware, such as Zeus or SpyEye), browsers do not launch correctly or open blank, unusable windows.

    Right now, possible solutions are:

    • stop Rapport service, launch web browser, start Rapport service;
    • uninstall Rapport, or
    • remove web browsers from the list of programs protected by EMET.

    Neither of these is a good one.

    This is just FYI, I see the fault at Trusteer's side.

  • On 64-bit Windows 7 SP1, mmc.exe (Microsoft Management Console) will crash on launch if it's included in the protected apps.  This has been observed on multiple systems, it's repeatable.

    A component of a fingerprint-reader's software suite crashes if it's included in EMET's protected apps.  The software in question is the Protector Suite, available for purchase or a free trial here:  The component is psqltray.exe.  This also is repeatable on two systems.  Update:  as you may have suspected, EAF is the culprit.


    Other than that, things have been pretty smooth sailing with EMET applied to an extensive list of apps on Win7 and one recently-retired WinXP box.  From past experience, I know not to set system-wide DEP to Always On or I won't be able to make DEP exceptions.

    If you want to make the exploit writers break out in a cold sweat, consider adding an EMET-driven mitigation module to Microsoft Security Essentials.  You could generate a "safe list" of high-profile targets that EMET can be safely applied to, the usual stuff like Java, media players, VoIP and email clients, etc, and distribute updated lists as part of your signature updates.  Label it with a user-friendly euphemism like "Enable anti-exploit features."

  • With Windows Server 2008 R2 SP1 as Hyper-V Host and Hyper-V Guest the EMET 3.0 EAF Mitigation may cause applications like Internet Explorer 9 x86 And Adobe Reader 10 to run about 10 times slower (means at 10% of speed without EMET/EAF). When you disable only EAF applications run fast. This should be mentioned in the EMET documentation as Hyper-V/EMET/IE are all supported products and it should be possible to disable individual mitigations for a whole system through Group Policy.

    You may use <> to compare. But don't compare IE 9's result with other Browsers or you might cry ;-(

  • I would like report that the 32 bit versions of Windows Media Player and Wordpad within Windows 8 Release Preview 64 bit are not compatible with the SEHOP mitigation of EMET 3.0 or EMET 3.5 Tech Preview.

    Please see the following threads for details:

    Windows Media Player (post dated: 12th October 2012):

    Wordpad (second post dated 26th July 2012):

    Finally, the 64 bit version of Apple iTunes (iTunes.exe) is not compatible with the system wide i.e. global SEHOP setting(Application Opt-Out) when installed on Windows 7 SP1 64 bit.

    Please see the following thread for details (post dated: 5th October 2012):

    EDIT: 21st April 2013: In the above thread, the version of iTunes was 10.7 64 bit. Version 11 and higher of iTunes 64 bit are not affected by this issue. I have used iTunes to purchase tracks from the iTunes Store without issues even with system wide SEHOP enabled.

    I hope this helps. Thank you.

  • updating to Chrome Version 23.0.1271.64 m and Chrome in EMET (all checkmarks on) crashes several extensions. Uncheck SEHOP for chrome solves the problem.

    If you think that might be a security problem in Chrome, then give google support a hint. For me as private person its a little bit difficult to contact the right channels.

    As noted by David G.1 (above), Dropbox is not compatible with the EAF mitigation of EMET. I can also confirm this for version 1.6.4 (released yesterday) when installed on Windows 7 SP1 64 bit.

    Dropbox is compatible with all other mitigations from EMET 3.5 Tech Preview.

    For your information, Dropbox works with system wide DEP (Application Opt-Out)(always on) and SEHOP (always on)(Application Opt-Out) applied.

    I hope this helps. Thank you.


    Off Topic:

    I have submitted a feature request with Dropbox to add DEP, ASLR and /GS security mitigations to Dropbox by default.

  • Some technical background for this repeatable issue:

    OS: Windows 7 Professional, SP1 (64-bit), upto date patches
    EMET: version 3.5
    Browser: IE 9.0, ROP protection enabled
    Application: SnippingTool.exe, version 6.1.76

    Issue: When trying to capture some of the content within Internet Explorer with the Snipping tool, the system freezes and only the Task manager is available. EMET Notfier logs this message:

    EMET_DLL module logged the following event:

    EMET encountered an error in 'C:\Program Files (x86)\Internet Explorer\iexplore.exe'
    CallerCheck Failed:
      PID          : 0x1508/5384
      TID          : 1184
      API Name     : kernel32.VirtualAllocEx
      ReturnAddress: 6AF9B294
      CalledAddress: 7644D998
      StackPtr     : 0014DC64

    Capturing image with Snipping tool within any other applications or browsers with ROP protection enabled does not result in this error. Ending task for IE through Task Manager unfreezes the system and Snipping shows the captured image; however, ending task for Snipping does not unfreeze the system. EMET ask, "Do you want to resume?" Selecting "Yes" results in more EMET notifications, conversely, selecting "No" keeps the system frozen.

    Disabling all ROP mitigation for IE resolves this issue. Removing the check mark for the mitigation identified as "Caller" only also resolves this issue. It seems that Windows SnippingTool.exe application code isn't "secure" and might be the next attack vector for hackers for Windows. In either case, IE should freeze the whole system.

  • After installing EMET 3.5 on Win7/64.  Now AOL will not run.  Says out of memory.

    I uninstalled EMET, but the problem persists.  Clearly EMET is leaving some registry settings behind when it uninstalls.

    I went to the advanced system settings control panel, and now I see the DEP settings are all greyed out.  I used to be able to turn DEP on and off here, but no longer.

    I tried rolling back to a system recovery point before installing EMET, but that was no help.

    How do I fix this?  Should I reinstall EMET and use it to make an exception of AOL, or what?

    How do I get the advanced system settings control panel to let me set DEP settings as it used to?

    Can we get EMET fixed so that it uninstalls better?

    PS: On a hunch, I reinstalled EMET 3.0, set settings to recommended, then rebooted.

    Now AOL works again.

  • Hi FAntonio2,

    You are correct, AOL will give this error when system wide DEP is enabled. Since the option of turning off system wide DEP is unavailable to you, the following thread may be of assistance to you. From what I can tell these steps only apply to Windows XP:

    The steps that apply for Windows 7 (they should be the same for Windows Vista) are mentioned in the following thread:

    I hope the above information is of assistance to you. Thank you.


    EDIT: Thanks for your update FAntonio2. If re-installing EMET and setting it to recommended setting had not resolved the issue, the threads I linked to above would have been the next steps. Thank you for providing the solution that worked for you.

  • Running EMET 3.5 Tech Preview on Windows XP SP3

    Word 2000 SP3 and Excel 2000 SP3 running well with all mitigations on, including the DEP that both the .xml protection profile and the EMET guide listed as incompatible in the later Office XP. 

    Both Word and Excel have all patches up to their end-of-life date in 2009.
    Caveat: I have an older Pentium 4 that does not support hardware-based DEP; my DEP is the software-based variant.  This might be the reason why DEP did not crash the applications.

    Some other software not listed in the EMET guide that are also running all mitigations, with no issues:
    Rhapsody (the standalone application for music streaming and searching)

I have EMET configured to opt out explorer.exe for all protection types, but it still crashes and EMET reports it did a DEP mitigation.

  • Hi Lucas Z.,

    I would suggest simply removing explorer.exe from being protected by EMET. I have not seen this included on any tried and tested list of applications to protect with EMET since explorer.exe is a crucial process that must remain stable.

    Since you are running Windows 7 64 bit (your exception shows this, namely BEX64 and Application Version: 6.1.7601.17567. 6.1.7601 is Windows 7 with SP1) explorer.exe already has DEP, ASLR and /GS (Guard Stack) v2 enabled and this should be enough protection.

    Here are 2 examples of such lists of applications to protect. The first link cautions you about what applications you add to the list, especially for operating system processes.

    If you wish to troubleshoot this issue further, please create a new thread (topic) in this forum.

    Thank you.

    Application Name: C:\Program Files\Internet Explorer\iexplore.exe

    CallerCheck Failed:

      PID          : 0xF74/3956

      TID          : B68

      API Name     : kernelbase.LoadLibraryExW

      ReturnAddress: 6FFF0D2C

      CalledAddress: 7606B8B1

      StackPtr     : 0331BB90

    Also I registered on this site to post this and wanted to make the error a screen shot but every time I try it gives me an error about I am not allowed to add photo till my account email is checked. I set up alert me and received a confirm email. It has not been 24 hours, do you have to wait longer or can someone tell where to write to get this fixed. thanks Lynn

    EDIT I did not know about registry files to delete. So uninstalled, only found one registry file to delete the, HKLM\Software\Microsoft\EMET. And then reinstalled, so far no errors. I have started another post about settings to import.

  • Hi Lynn53,

    Thanks for highlighting this issue.

    Due to the variety of add-ons that Internet Explorer may have installed, an incompatibility with a mitigation can be expected. Thanks for pointing out which mitigation you disabled in order to resolve this.

    What you describe in relation to the registry keys sounds fine. Another forum user, Quitch mentioned this in the following thread:

    I have also only found 1 registry key that was present to delete.

  • Hi JamesC_836, after importing the Popular and Recommended settings started getting the pop ups again. Removed the checkmark for ROP Caller iexplorer and they have again stopped. Just wanted to report this for others.
    Should add that the checkmark had been  added with the new install of EMET that I did.

  • Hi Lynn53,

    Thanks for your update.

    In an effort to narrow down what is causing Internet Explorer to close due to the ROP Caller Checks mitigation, would you be willing to re-enable this mitigation and try to use Internet Explorer without add-ons? This is a temporary mode of Internet Explorer.

    If Internet Explorer continues to work correctly in this mode, you will then have determined that an add-on for Internet Explorer is causing this issue. The support article linked to below describes how to this. Disabling add-ons one by one is also mentioned.

    While not every security mitigation of EMET is compatible with every add-on, if the name of the specific add-on causing the issue can be determined, it may be possible to fix this compatibility issue.

    Alternatively you can simply leave the ROP Caller Checks mitigation disabled and continue to use Internet Explorer as normal.

    I hope this helps. Thank you.

  • Well I disabled all IE add ons and was still getting the errors. I have four computers, the one with the problem is an old vista that I installed a fresh windows 7 so I would not have all that useless junk. I also use it for testing and learning as the reason this is the only one with EMET v4 the others have v3. I have Winpatrol Plus program I have been trying out, I stop it from loading at startup and thought that was the problem so uninstalled it but now am still getting the errors, so that was not the problem. So I have eliminated the IE add ons and Winpatrol as the problem. The only other thing I can think of is I have Avast Pro antivirus. What do you think I should try next JamesC_836.

    Edit, disabled Avast and still getting error, so Avast has been eliminated as the problem.

  • Hi Lynn53,

    Thanks again for your update and for the thoroughness of your testing.

    Among my PCs, I also have a Windows Vista 64 bit SP2 PC with EMET v3 loaded. I have found that settings that work perfectly on Windows 7 64 bit do not work as well for Vista. I am not sure exactly why this is. I have had to customize EMET settings to keep 3rd party programs on Vista working smoothly.

    My advice would be to leave the mitigations disabled that are causing the issues. This is an advantage of EMET it can provide extra protection while maintaining compatibility/usability by simply turning off mitigations that crash programs. The settings that you mentioned earlier today seemed to work very well.

    Thanks for testing and eliminating Avast and WinPatrol as potential causes. Please feel free to re-enable Avast and re-install WinPatrol and set them up as you have found to work best for you. Please also feel free to use Internet Explorer as normal with EMET settings that do not cause it to crash but still provide the best protection. Apologies for any inconvenience that this testing has caused.

    I am sorry that I can’t provide more specific advice but with the different combinations of programs that each of us use we need to find what settings work best for us and continue to use them.

    I have marked your above post as helpful since you have carried out a lot of testing which will benefit others.

    If I can provide any further assistance, please let me know. Thank you.

    EMET 4.0 Technical Preview System Settings settings as follows,

    DEP - Always On

    SEHOP - Application Opt Out

    ASLR - Always On

    Certificate Trust - Enabled.

    Regression testing against 3.5 results in,

    Outlook 2003 now works fine whereas in EMET 3.5 it failed when ROP caller check was active, so something


    MS Money 2005 UK now fails with Caller Check error but in EMET 3.5 it failed with a DEP error.

    Currently happy to switch ROP caller checking off for this application.

  • Every could of days a random Windows 7 64 bit user will have an issue when running EMET 3.0 and Microsoft Office 2010 looking at a known good document, where one of the Office apps they are using will crash with a DEP error when opening or closing the application.  This is logged in the Windows Application logs as an Error:

    Source: EMET
    Event ID: 2
    EMET_DLL module logged the following event:
    EMET detected DEP mitigation and will close the application: C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE

    The next second, another log will be generated:
    Source: Application Error
    Event ID: 1000
    Faulting application name: WINWORD.EXE, version: 14.0.6129.5000
    Faulting module name: log4cxx.dll_unloaded, version:
    Exception code: 0xc0000005
    Faulting application path: C:\Program Files (x86)\Microsoft Office\Office14\WINWORD.EXE
    Faulting module path: log4cxx.dll

    This has happened for "Faulting module path" values of: log4cxx.dll, unknown, PGPlsp.dll, and others.  The Office application may be different for each.

    This seems non-repeatable but an occasional random occurance. 

    Tuesday, April 30, 2013 10:00 PM
  • Hi Chris,

    The log4cxx.dll is a DLL related to Nero CD/DVD Authoring software and is included with Nero Burning ROM. It is possible that this DLL is being loaded by Word 2010 through an Add-in (another less likely possibility is that this DLL is being loaded into Word via the AppInit_DLLs value within the Windows Registry since Word does load user32.dll).

    Please find below links describing how to disable such add-ins. This should prevent Word from crashing in the future.

    PGPLsp.dll is related to the Symantec PGP Desktop encryption product. Since this provides encryption for sensitive data, I would advise against removing this particular add-in.

    If the Windows Registry is being used to load these DLLs additional steps will be necessary to remove them.

    I hope this helps. Thank you.

  • You're welcome, Chris.<o:p></o:p>

    I am not sure if what I mentioned about add-ins for Microsoft Office helps or not. If you need the functionality they offer, the only remaining option is to disable
    the DEP mitigation of EMET
    for any Office application that uses these add-ins. Also ensure that system wide DEP is set to Application Opt-in (or essential Windows programs and services only option within the Windows Control Panel).

  • We have identified one Office EMET 3.0 DEP issue as correlating with a separate Cisco Click to Call plug-in error in the OS application logs.  Other EMET Office 2010 OS application crash logs, mostly DEP related, occur every now and then across our workstations randomly and non-repeatedly with known good documents and have no correlated plug-in OS application log messages, so I am unable to troubleshoot.

  • I had EMET V3.5 Tech Preview installed for a long time on Windows 7 and since inception on Windows 8 with no problems.

    I uninstalled V3.5, restarted Windows 8 and installed V4.0.4913.26122 and all of: Adobe Acrobat, Lenovo Hot Spot Service, Skype C2C Service, Internet Explorer and DU Meter failed with KERNELBASE.dll errors. Acrobat and Internet Explorer would not even start.

    I had installed V4 with Recommended Settings.

    I uninstalled V4, restarted, and reinstall V3.5 Tech Preview. This substantially reduced the errors.

    I again uninstalled V3.5 and this time removed the two EMET Registry Keys. I restarted and installed EMET V4 with no setup.

    I then added about a dozen and a half programs manually:  All of Office 2013 including ONENOTEM, Adobe, both iexplore (32 and 64), Java, and jusched, integratedoffice, and PopPeeper (email daemon). I then imported the certificates file.

    Time will tell if this bizarre and worthless Windows 8 system will just keep crashing.

    With over 150 processes and 12 flags, adding one each day to test will take 1800 days to set it up. EMET V4 was not made for mortal human beings and yet mortal human being are precisely the ones that need it.

    Edit: The FoxIt crash with SEHOP does not happen on a second PC, all the versions are the same, the only difference is the working system has a Core 2 Duo CPU and the problem PC is a workstation with dual older XEON CPUs.  We've had several other applications that acted up on that XEON PC, in one case it was tracked down to a libgnutls26 bug that only happened on CPUs that have MMX but not SSE2.

  • AQTime 7 by SmartBear is a .exe profiling application used by software developers.

    I cannot disable the "SimExecFlow" check for this application, no matter what I try.

    I added an entry to AQTime.exe and all other *.exe files installed by the application. I disabled all mitigations for all these executables. But when I start AQTime, EMET always detects a SimExecFlow, even if that checkbox is off.

    The only way I can run AQTime is to switch from "Stop On Exploit" to "Audit Only". EMET will display the "SimExecFlow" detection for AQTime.exe but the application itself continues and works as expected.

  • If you boot with a Windows Mobile device connected (at least when connected via USB), Windows Mobile Device Center (v6.1.6965) crashes on startup. You can start WMDC once the system has finished startup, and you can plug a device in after startup, either way WMDC will work fine. But if you startup with a device attached, WMDC try to start and will crash. This is with EMET 4.0 on Windows 7 Ultimate x64. Did not have this problem until after EMET was installed. WMDC services are set for Auto (delayed) start. WMDC is runing under EMET with all mitigations enabled.

    Also Speedfan 4.49 will not run under EMET. It fails with a SimExecFlow error. And seems to "load" in EMET twice or something. I had to disable all mitigations and remove it in the list in the Applications Configuration window, and again in the Running Processes list in the main window. I tried adding each mitigation separately, to see if a specific mitigation was the issue, but it simply would not work if any of the mitigations were enabled in EMET. Same computer as the WMDC issue.

  • I'm also experiencing a "SimExecFlow" error when using a specific application - even if all mitigations have been turned off. You have to actually remove the app from the apps list. The apps concerned are the DirectShow filters subsumed under the name "LAV Filters" ( If their ffmpeg part is compiled using gcc 4.8.x EMET will close them upon start. I'm testing it with the MPC-HC media player 1.7.1 (it comes with LAV Filters built in, so you don't have to download those extra), download below:

    Tested with EMET 4.0 and EMET 4.1 under Windows 7 x64 SP1.

    To reproduce:

    Add mpc-hc to EMET list (or possibly other DirectShow players), open mpc-hc and make it use one of the LAV Filters by opening a file that needs them or changing their settings. (For the built-in ones: Options>Internal Filters>[one of the bottons at the bottom])

    This problem can be solved as follows:at the command prompt as Administrator regsvr32 /u certsentry.dll and prohibiting in Group Policy application execution certsentry_setup.exe. Though the course is a crutch.

  • EMET 4.0 with Outlook 2010 & CRM 2011 Plugin - Outlook crashing -stackpivot to fix

    I realize I can disable the stackpivot check however what if there is a real stackpivot vul that isn't CRM related? We would be unprotected. That and I thought MS products were EMET certified? I suppose I can ask them...

    In fact EMET isn't actually closing outlook when the stackpivot mitigation happens. We are just getting a lot of EMET alert (noise) emails.

  • Outlook 2007
    SalesForce For Outlook plugin

    Login to SalesForce via the plugin. Outlook will crash and notify user about SimExecFlow. Turning this option off gets rid of the error.

    My idea of a party is a virtualization server and a room of TechNet DVDs

    Tuesday, January 21, 2014 10:59 PM
  • Turns out a reinstall of the CRM plugin fixed some cobwebs and EMET is no longer alerting on Stackpivot.

    I'd also like to point out that telling people to just turn off the mitigation kind of defeats the purpose of EMET. It is there to let you know you have some software doing bad (malware-like) things...and the correct action would be to fix said software. In the case of Outlook, I did not want to turn off any mitigations. Perhaps for small corner case LOB apps that is more doable.

  • Just as an FYI I've started a spreadsheet with issues. If you could when reporting add them to the spreadsheet it will help the community and us (MSFT) to tailor installs to our organizations as well as help drive to resolution issues that are encountered. is the wiki page however due to formatting issues the actual data is hosted in an Excel Web Page instead located at which should be open to all to edit.  Try to fill in fields as much as possible to help out when you encounter app issues.  The first page in the workbook is EMET mitigations which are the specific emet.dll injection mitigations provided to applications, the 2nd page is the System-Wide Mitigations (DEP/SEHOP/ASLR) which realistically are not EMET however can be controlled by EMET so if you do have a system-wide protection mechanism crash post it on the 2nd page.

    Thanks for your help with this :)

    Settings for Vlc.exe are proposed in popular software.xml

    Up to version 2.1.2 of vlc those settings are compatible.

    vlc 2.1.3 is not compatible with SimExecFlow.

    EMET notification: "EMET detected SimExecFlow mitigation and will close the application: vlc.exe"

    right after vlc.exe start.

    This has been reported as h...://

    There are also posts about this incompability as

    As the incompatible setting is part of a proposed and predefined set of settings this might be of interest for you.

  • Your EXEL ONLINE spreadsheet should be formated as table in order to let everyone be able to see table headers, even if doing edits in in high numbered rows.

    "Format as table" is available in web interface but there seems to be no obvious way to correct/revert table format for "everyone" users.

    So it might be necessary for Support personal to have a look at that table and think of a practical solution for this comfort/accebility problem/feature.

    Thank you.

  • I don't see anything here about windows update.  If anyone else has this problem I'd be interested in the solution.  Since EMET install time, I always receive error code 80244019 when trying to run windows update.   I have switched to downloading them manually when they appear.   I'd like to know how to enable EMET to allow windows updates to work again.  Have reinstalled the update services and tried stopping and starting a variety of services to re-enable Windows Update. I'm not sure how to turn EMET off... thought about uninstalling but figure if it even blocks the big virus we call windows update, then it can't be all that bad. But, it would be nice to get that automated process working again.

  • Hi everyone,

    Using Google Chrome Beta v34.0.1847.11 with EMET 4.1 when installed on Windows 8.1 64 bit resulted in the Caller Checks mitigation needing to be disabled for Chrome to continue to launch. This did not occur with previous versions of Chrome.

    Disabling all extensions (using chrome://extensions) and plugins using (chrome://plugins) still resulted in the same change to EMET being necessary.

  • Hi everyone,

    I have completed some initial testing of EMET 5.0 Technical Preview (TP) on Windows 7 64 bit and Windows 8.1 64 bit and wished to share my findings.

    In general, EMET 5.0 TP with Windows 7 64 bit SP1 needed many changes to its configuration to prevent application crashes either on start up or on exit (mostly on exit). For Windows 8.1 only Google Chrome needed a settings change to prevent it crashing on launch. I have provided a full list of settings below with the config files downloadable from my OneDrive.

    According to the following forum thread (and the link below) the many Windows Error Reporting dialogs that are encountered are due to a bug in this preview version of EMET:

    Many thanks to Susan Bradley for highlighting this issue and the multiple ASR prompts issue.

    Only the necessary changes to the default configuration of all mitigations being enabled are mentioned below:

    In all cases (Windows 7 and Windows 8.1), EAF+, Anti Detours, Banned Functions and Deep Hooks remained enabled.

    In addition, only the minimum number of changes needed to have an application work correctly are shown.

    The system wide settings for EMET for each version of Windows are provided in the following screenshot links:

  • I suppose an experienced user would understand about getting applications recognized within the interface but in general I find it hard to navigate.  After months of problems with Windows Update (first installed 3.5, upgraded to 4.0 then 4.1 and finally 5.0) I gave up and uninstalled EMET but after some thought, attempted a reinstall and now the Windows Updates are working.   That's curious.   I accepted default configurations on all builds.  The reinstall was build 4.1.    I see no one else with Windows Update problems so I can assume I am alone with the problem but it is clear that the interface is rather unfriendly as all here seem to have issues with ASR and ASLR.

    On the KREB's site, there is talk about something in the lower right corner that only exists as a refresh button on the versions I've seen.   I suspect that website may be outdated and misleading.   I think it is open season on someone with a good website explaining how to configure the EMET and especially tricky for the EMET developers to find a way to make the interface more user friendly and the tool bar less cluttered with options.

    My two cents.  But I like the product regardless of its awkward handling.

  • If you apply any ROP mitigation to iexplorer.exe (I'm using IE11 on Win7x64), Quarri MyPOQ's protected browser will crash.

    I'm now using EMET 5.0 RP2.

    BTW, am I only one who experience occasional crash of flash player when I apply Heapspray mitigation to firefox.exe & plugincontainer.exe and watch Flash videos?

    It happens from time to time, not always, and remove Heapspray from both resolve the problem.

    Also when I set ASLR in AlwaysOn, Comodo Cleaning Essentials couldn't finish it's scan.

    It always stops (not crash, just silently ends) at Program Files\Internet Explorer\en-US\eula.rtf.

    Putting back ASLR to Opt-in resolve the matter.

    However, last time I used CCE was several month ago. I'll confirm and maybe report to Comodo when I have a time.

  • Java 7 Update 55 requires SEHOP to be disabled as well (Win 8.1 Pro, x64, IE11).
    Friday, May 09, 2014 5:09 PM
  • Sorry again, I somehow missed your reply.

    Well, similar but different.

    AFAIK, so far CertSentry's function is gathering statistical info about certificate revocation checking system, so in the default setting it doesn't offer any additional protection.

    But you can make it enforce revocation checking for all apps which uses Microsoft CryptAPI so it protects a user from being fooled by revoked certificate.

    OTOH, EMET's pinning demands certain website to show certain certificate (exactly speaking, certificate which belongs to certain root CA), it works when a CA is compromised or made a serious mistake,  malicious people get completely legitimate certificate(s), and then abuse it e.g. launch malicious website with the certificate while trick people by DNS poisoning, or more likely uses the cert for MITM attack.

    EMET can prevent such attacks proactively, but CertSentry (with enforced checking) can help only after the CA revoked those compromised certs.

    BTW Chrome has same function as EMET pinning.

  • Hi, I'm using Windows Server 2008 Enterprise (Build 6002, SP2) 64-bit English running as the only productive domain controller, IIS and SQL-Server and I updated EMET from 4.1 to 5.0TP2 and after reboot the system didn't start anymore. First I had to circumvent a hardware problem (with a monitor connected, the harddrive doesn't start), then I couldn't log in due to missing cached credentials (I always log in remotely) and couldn't find the DomainAdmin password. Finally I could log in with SafeMode+Net, but uninstalling EMET is not possible in SafeMode. After I got that solved I could boot again. Trying to install EMET4.1U1 caused the same problems. It seems like the following applications are crashing, sometimes with error "DEP detected", sometimes they simply crash and EMET doesn't even detect the module. But finally, with some tweaking, I got it working. Here's the list of non-compatible programs, all of them don't work with EAF (Export Address Table Access Filtering) and run fine with EAF turned off (all are .exe):

    • EMET_GUI
    • EMET_Agent
    • Explorer
    • mmc
    • taskeng (Task Scheduler Engine)
    • Dwm (Desktop Window Manager)
    • lsass (*)
    • lsm (*)
    • services (*)
    • svchost (*)
    • w3wp
    • inetmgr
    • dns
    • ismserv
    • msdtc
    • spoolsv
    • dfssvc
    • inetinfo
    • DFSRs
    • NamecheapDDNSClient
    • sqlservr
    • sqlwriter
    • iexplore

    The ones with the star (*) are responsible for not being able to boot. All generic options are enabled or at highest level.

    Why is EAF for most applications not working? Is there some general incompatibility with Windows Server 2008? Would you recommend to turn off EAF for all applications, even for those that seem to work (like RegEdit)? Or is the machine pwned?

    Update: Unfortunately, adding a number of variations of the path including just "chrome.exe -Caller" into the group policy "Application Configuration" section didn't work to override the setting for Chrome used in the "Default Protections for Popular Software" section of group policy.  To get it to work we had to manually change the chrome line in the group policy .admx file to "<string>*\Google\Chrome\Application\chrome.exe -SEHOP -Caller</string>" and then change the Popular Software section in group policy to Not Configured and then Enabled again.

    I was able to get EMET 4.1 Update 1 to work by turning off every mitigation except DEP, SEHOP, NullPage and BottomUpASLR.  I had to use a config file.  If I use group policy to enforce mitigation, the java virtual machines crash.

  • Install McAFEE HIPS 8 Patch 4

    When the Microsoft Enhanced Mitigation Experience Toolkit (EMET) software is installed on a system running the Host IPS software and the EMET "Deep Hooks" feature is enabled, any application that is hooked by both EMET and Host IPS will become unresponsive on start up.

    When Host IPS functionality is enabled, along with Microsoft EMET "Deep Hooks" functionality, both products attempt to protect an application with similar hooking functionality. 

    This issue is resolved for Host IPS 8.0 in Host IPS 8.0 Patch 4, released in February 2014. For known issues, see KB78494. For Release Notes, see PD25043.

  • It seems as though there are a lot of issues with this, is it really worth it?  I am sure it is not for me as I don't understand most of what you folks are talking about.  I was really hoping that I could use this on my XP System but I don't know it I want the headache.

    Also interested in why the members here don't have there configuration posted so that others will be able to utilize this information properly?

    Oh, I am sorry It appears this is just for reporting issues? I will look around to see if I can post questions somewhere.

  • I haven't experienced PSI issue.

    I made DEP setting AlwaysOn and even added psi.exe, psia.exe and psi_tray.exe into app config, disabled EAF+, LoadLib, caller, and SimExecFlow (not because specific problem, but just to avoid unexpected problem as those mitigation often cause problem), then no problem found.

  • It's not an issue, but it is how ASR mitigation work.

    If you don't want it, you can configure ASR mitigation in iexplore.exe.

    In app config screen, select iexplorer.exe and click "Show All Settings".

    Then remove scrrun.dll from ASR tab.

    BTW, I admit it's annoying every time we have to see ASR warning when it comes into play.

    I made custom rules for Adobe Reader which disable scripts, 3D contents, and flash.

    Then every time the reader try to use those function, warning come.

    I want to DISABLE ONLY ASR WARNING while keep all other warnings active.
