dllhost.exe application error

    Question

  • hi.

    ive been having a "dllhost.exe - Application error. The instruction at 0x77724775 referenced memory at 0x5667bcbc. the memory could not be written. click ok to terminate the program" message when i try to open my programs. also after a while i get a similar message but its "taskeng.exe - application error....." instead.

    first off, yesterday i stupidly deleted the files in my prefetch folder. all the files. i can't say i know what i was thinking so i firmly blame it on the hunger i was feeling at that moment. i have been looking for ways to restore the folder to no avail. now when i try to open it, it doesn't even open. asks for admin permission but does nothing. it just remains at the windows folder.

    could this be the cause of the error or might it be something more sinister?

    also, i had a game open at the time i deleted the folders and shut down my system. now the game runs but the particular saved game i was playing seems to be corrupt.

    is there anything i can do or do i have to re-install windows? also, i dont have much experience with reinsalling windows 7. is there a way i can do it without losing my files and applications? i seem to remember doing that a couple of times with XP (i might be having another hunger moment though).

    thanks for any help and assistance.

    im using windows 7 64 bit, 2gig ram, core 2 duo t5450 processor @ 1.66Ghz

    Edit: actually the dllhost error comes up when i try to enter the prefetch folder. might be because of it asking permission though

  • Try uninstalling avast! See if that solves the problem.

    Then install the last version you had and use the automatic updates settings for the program update.

    If you can't uninstall it try using:

  • Hi,

    please download this reg file from my SkyDrive:

    http://cid-128fc518635be2dc.office.live.com/self.aspx/.Public/MS%20Foren/Registry/WER%5E_dllhost.exe.reg

    and make a double click on the file to import it.

    When the DLLHost.exe (COM surrogate) crashes, Windows Error Reporting Service [1] creates a dmp file under C:\Localdumps. Please upload the file to your public Skydrive [2] folder and post the link here. I take a look at the dump with the Debugger, maybe I can see which Video Codec is the cause.

  • i've downloaded it and run it but there is no C:Localdumps folder. It has never even brought up the Windows Error Reporting Service.

  • Did you have new DLLHost crashes since applying the reg file? Is the Windows Error Reporting Service disabled on our PC? In this case no dumps are created.

  • I have a similar problem, but the error pops up when i sometimes right click on desktop ..at startup and and when I Single click any file in explorer. Nothing crashes so solution window doesnt appair.

    I dont know how it started, but either it apaired because of windows update or because of Tuneup program I have ..which automatcally runs in background cleaning cache, registry etc.

  • You may do a system restore. If it does not help, run In-place Upgrade to repair the system.

  • Most likely I had the exact same problem you described when I manually updated avast! to the 5.0.889 build Best thing to do was roll back using system restore.

  • hmmm. i did just update avast (5.1.889, not sure what the last version was though as i hadn't updated the program in a while)  so that might be it. unfortunately i turned system restore off a while back and forgot to turn it back on. oops. how can i remedy this?
