  • The full error text is as follows:

    Error 25004: The product key you entered cannot be used on this machine.  This is most likely due to previous Office 2010 trials being installed. (System error: <hresult>)

    The key you are currently trying to install with, is an Office Professional Plus Trial key. A machine will allow one Professional Plus Trial key installed on it ever. Meaning you can install a trial on a machine, used it for some time, uninstall Office. When you go back to the Microsoft website and get a new key, the second installation will be rejected with the above error message.

    If this is not how you ran into the situation, please let us know the exact (System error: <hresult>) in the above error message.

  • Dear Powered,

     

    The issue may occur when the previous Office files on the computer are not completely uninstalled, such as Office 2010 beta. We can try to completely uninstall Office program and then install Office 2010 again.

     

    First, please go to Start > Control Panel > Programs and Features (Add/Remove Program Files), Locate the Office program and uninstall it.

     

    Then, you can try to manually uninstall Office programs by the steps below: 

     

    1. Download and install the Windows Installer Cleanup Utility.

    http://download.microsoft.com/download/E/9/D/E9D80355-7AB4-45B8-80E8-983A48D5E1BD/msicuu2.exe  

     

    2. After you install the Windows Installer CleanUp Utility, click Start  -> All Programs -> Windows Install Clean Up.

    3. Highlight Microsoft Office 2010 entry in the list and then click Remove. Quit the Utility.

     

    Note: If you have got any other old or redundant office entries such as Office 2007 or other Office standalone products, such as Visio in the list, please remove them together.

     

    4. Close all applications.

    5. Click Start  -> Run, type "regedit" (without the quotation marks) and press Enter.

     

    6. Expand the registry tree on the left pane and locate the following two registry subkeys:

     

    HKEY_CURRENT_USER\Software\Microsoft\Office

    HKEY_LOCAL_MACHINE\Software\Microsoft\Office

     

    7. Right-click on this registry subkey and click Delete to delete those keys.

    8. Open Windows Explorer, and then browse to the "C:\Program Files" folder

     

    If it exists, rename the "Microsoft Office" to "Microsoft Office OLD"

    If it exists, rename "OfficeUpdate" to "OfficeUpdateOLD"

    If it exists, rename "OfficeUpdate14" to "OfficeUpdate14OLD"

    If it exists, rename "OfficeUpdate12" to "OfficeUpdate12OLD"

     

    9. Click Start  -> Run, type "%Temp%" (without the quotation marks) and press Enter.

     

    10. Empty the Temp folder.

     

    Note: If some files can't be deleted, please skip them, which don't influence the result of the troubleshooting.

     

    11. Empty the Recycle Bin.

     

    12. Restart your computer.

     

    13. Try to reinstall Office 2010 again.

     

    Please take your time to try the suggestions and let me know the results at your earliest convenience. If anything is unclear or if there is anything I can do for you, please feel free to let me know.

     

    Best Regards,

  • Just physically purge  all the Office apps, folders, registry and restart the Workstation

    but still got the error message at the end of the installation

  • Dear Powered,

     

    I am sorry to hear that the problem persists. To better check the situation, I would like to confirm where you get the Office program and the product key. Is it the Office 2010 RTM version?

     

    Please make sure the product key is associated with the Office program. For example, if this is an Office suite, the product key should also be the key for the suite.

     

    Best Regards,

     

    Sally Tang

  • Hi Powered,

     

    Is your Windows XP system 32-bit version? Also, did you download the 32-bit version of the Office Professional Plus 2010 program.

     

    For the detailed information about the system requirement, you can refer to this article:

  • I'm having the same issue on a brand new Dell studio XPS 64 bit.  It's never had Office installed, I've followed the instructions shown here http://www.programimi.com/2010/04/26/fix-problems-upgrading-office-2010-beta-to-rtm-final-release/  which have apparently fixed a lot of peoples issues, but I'm having no joy!

     

    Has anyone got another fix for this please!!!!!

    I have the exact same error. However I installed Office Professional Plus 2010 (14.0.4730.1010) from Technet thursday last week, then uninstalled it as I thought the install file had errors. I then downloaded Another trial but then with a different serial but it won't let me install. I did a complete purge of the entire system - all office files except for HKLM/software/microsoft/office which cannot be deleted. I just want to know if there is a way to find that original trial key cuase i have like 20+ left.

  • I do have the same problem, I downloaded Office 2010 Professional on 6/20 and still struggling with the installation.

    FYI, I dont have any office folder in Program files nor in Registry. Did a sweep with CCleaner as well, no luck!

    I really wanted to know whether there is any option to regenerate that trial key from the Microsoft downloads section (It looks like a bunch of keys generated during a particular period has caused the issue... Just guessin...)

    More Info: OS is XP SP3 Guest in Mac OSX 10.6.4 Host (Running inside parallels)

    Wednesday, June 23, 2010 4:42 AM
  • Same problem here as well.  The only version of 2010 I had installed prior to this was the beta.  Maybe they consider the beta itself as a "trial version"?  

     

    Saturday, June 26, 2010 3:30 PM
  • No answer?? Anyone??
    Sunday, June 27, 2010 4:38 AM
  • Yes, this problem needs an answer, it will not just go away.  I am sitting here (a fully paid and registered user of Office 2007 who was testing Office 2010 BETA) without any version of Office now because Microsoft couldn't handle an upgrade, or more accurately because their COPY PROTECTION is BREAKING THINGS.   Arrgggg.

    Sunday, June 27, 2010 6:55 AM
  • I am really in the dark here.

    I have a clean installation of windows 7 ult /32 and installed the demo. I had a small problem so i removed and wanted to install it again. All I get is the shitty error. I have erased everything in the registry that has "office" on it, erased the temp etc. Still to no avail.

    I feel like we are being ignored here a little. Kind of reminds me of MSoft's standards in the 90's. Is it really so difficult to allow setup to re-enter a key as long as the first one hasn't expired? Even a immature programmer like myself could handle that.

     

    So please give us a solution that works

    Sunday, June 27, 2010 10:26 AM
  • Being ignored more than a little.  This thread was started on May 28 and it's almost a MONTH LATER.  I guess the Microsoft answer is that you should just buy the product and once you are dealing with a production code instead of a trial code it will "probably" work.  No thanks let's get this working as promised right now.  
    Sunday, June 27, 2010 11:42 AM
  • We little people in our righteous might will fight through to absolute victory!

     

    So M$oft give us an answer

    Sunday, June 27, 2010 12:36 PM
  • Same error here, not getting a reply anywhere.  Never installed any upgrades.  Ugh, I have just had problems every time I upgrade a Microsoft upgrade.  The email support told me "You don't need to uninstall 2010, if you want to keep it."  Which wasn't even close to the question...

     

    Can someone help us with this so we can pay youMsoft money to upgrade?

     

     

    Wednesday, June 30, 2010 12:51 PM
  • Tried all the suggestions - running fixit to remove installation, deleting temp files, removing registry entries  - no luck.   Could trial rely on some hidden file that is checked by MS installer that is not removed by "fixit"?  Also MS please stop sending me emails asking about how my trial is going.
    Wednesday, June 30, 2010 2:04 PM
  • The comment in this thread that is marked as the answer ISN'T the answer.  It is suggesting that a previous copy of Office 2010 Professional Plus Trial was installed, removed and then reinstalled.  For myself it was the BETA of 2010 then the trial of the release version that isn't working.  For others they are getting this error message even on "new" installs.  This thread needs to be marked unanswered and get some MS attention.

    WHY DID THEY JUST ADDED A FEATURE THAT CAN KEEP BOTH PROGRAMS!

    know look what they made me do,, i UNInstalled all previous programs

    NOW IM STUCK!! AND UNABLE TO DO MY POWERPOINT PROJECT!!!! THAT IS DUE NEXT WEEK!!!!!!!!!

    GRRRRRR.........

    Wednesday, July 07, 2010 12:35 PM
  • Same problem.

     

    Although it would not allow me to delete

    HKEY_LOCAL_MACHINE\Software\Microsoft\Office (even after a reboot)

    Saturday, July 10, 2010 10:22 PM
  • How is this error message even possible with Office 2010?  There were NO PREVIOUS Office 2010 trials available to be installed besides the beta.  For someone transitioning directly from the beta to the trial shouldn't there be a fix?

    Sunday, July 11, 2010 9:10 AM
  • same here, school is starting tomorrow and I can't imagine working with no office.
    Sunday, July 11, 2010 1:12 PM
  • Hahaha :( Just got this from Microsoft:

     

    "We're writing to remind you that your free trial period has now ended. You must upgrade to the full version to continue using Office 2010."

     

    Good one MS!

  • Same thing for me with a fresh install of Win7 64 bits !
    Wednesday, July 14, 2010 1:40 PM
  • I'm getting this problem too.

    I have Office Small Business 07. Downloaded the Office 2010 trial, installation froze halfway through.

    Used the Fixit to remove all traces of the install before starting again, but I still get this message, even with a different 2010 product key.

  • Please try running Office rearm:

    http://technet.microsoft.com/en-us/library/ee624357.aspx#section4

    The easiest way to do it is to open an elevated command prompt, then go to the folder:

    C:\%Program Files%\Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform\

    This will be in the "Program Files (x86)" folder if you're running 32-bit Office on 64-bit Windows.  If you saved to another drive other than C, then use the correct drive letter.

    This will allow you a grace period to run the Office trial.

    And i installed Office 2010 on a fresh install with no other Office installation previously done !

    Anyone can help ?

     

    Thank

  • WTF!!! I mean, c'mon, this is BS. First I get an error trying to install because I'm running security software on my computer... then when I remove that from start up and try to install again, it tells my that I can't because the SN I am using is already installed on my machine.

    This is the worst product installer I have seen yet from MS. I can guarantee that I will not be "purchasing" this version of office to use it.

    Like, it's now August and there is still no fix for this. Absolute BS!!!

    Sunday, August 22, 2010 7:09 PM

  • I have a similar problem. I get the install error when trying to install software purchased from Microsoft via Digital River.  The problem started for me when I uninstalled office 2010 from the "D" drive, backed up all of my files and deleted the "D" partition.  I then merged the free space with my "C" drive and now I can not reinstall.  i have tried every step here multiple times as well as a few others in various forums from Microsoft... Please Help.

    Are you running 32-bit Office on 64-bit Windows?  You may want to check the "C:\Program Files (x86)" folder.  The rest of the path is the same.

  • Office 2010 suites



    To uninstall the 2010 Microsoft Office suite automatically, click the Fix this problem link. Click Run in the File Download dialog box, and then follow the steps in the Fix it wizard.

  • I am having the same problem. This is how to fix it (easiest method to hardest)

    1. try using http://www.askvg.com/remove-product-key-of-microsoft-office-xp-2003-2007-and-2010-using-office-key-remover/ (this is not anything illegal) and then try installing office

    2. Try uploading your documents to skydrive and using the built in editor to edit your office documents (if you are desperate to do your projects and they are due the next day)

    3. try using better, free software that does NOT require you to go through copy protection, like Open Office (THIS IS NOT AN AD, I AM NOT AFFILIATED WITH THEM).

    4. Microsoft is getting on my nerves, lol!

    Saturday, November 06, 2010 7:25 PM
  • Hmmm, I think I know our problem is, I already read about this problem at Microsoft Office website and I read something that maybe the source of our problems here

    Here it goes, : For most software, trials can only be installed one time on a device.

    I get that information at http://support.microsoft.com/contactus/conversation.aspx by writing " The product key you entered cannot be used on this machine " then choose Trial Products

    Hope this will help you, but I still don't know how to fix it T_T someone help me too LOL :))

  • I may be able to help with those of you who are unable to delete [HKEY_LOCAL_MACHINE\Software\Microsoft\Office].  The reason you are unable to delete it is because registry keys are subject to permissions .   Permissions are security policy settings that restrict users from certain operations.

    NOTE: Backup your registry or create a System Restore Point before proceeding further

    Open Registry Editor (regedit.exe ) and navigate to the HKEY_LOCAL_MACHINE\Software\Microsoft\Office key and right-click Office and select Permissions

    A  Security tab will open with a list of users or groups who have been specified access privileges.  Without writing a dissertation on permissions, I will attempt to make this easy.

    Our goal here is to delete the Office key, so we need to grant YOU (your user name ) Full Control

    This is simple if the checkboxes are not disabled, which they are so here is how you break the inherited permissions:

    Click the line containing your user name and click the Advanced button.  At the bottom of the new window will be a checkbox Include inheritable permissions from this object's parent .   Clear the checkbox.   It will ask you if you are sure you want to remove inheritable permissions, choose yes and replace the inherited permissions with explicit permissions because the key will be deleted after we are done.

    It may take a few seconds to process the permissions, then click OK to return to the Security tab and checkmark the box Full Control and Allow then click OK to return to the main Registry Editor window.  Then you will be able to delete the Office key.

    My hypothesis is that this process will allow you to reinstall your copy of OFFICE, if you still desire to do so. 

    On another note, I virtualize my entire system with VMWare Workstation when I install beta software or other software I know I am going to uninstall later.  Oracle also provides VirtualBox free of charge which also allows you to virtualize the software you are installing, so that the installation does not actually change your true registry.  The sandbox you create maintains the changes the beta software thinks it has created.  When you are done with the software, you merely delete the sandbox and it is as if you never installed it in the first place.  I highly recommend sandboxing beta software or anything else you download off the Internet that is not verified with a certificate issued by a trusted certificate authority.  A sandbox will isolate viruses and other malware, protecting your true computer system.  (I actually prefer this method above those performance-sapping resident antivirus programs.)

    Good luck and let me know if this works for you or if you have found another solution to your problem.

  • Well didnt work at all. I guess i read and tried all stuff of all threads on whole web and none worked. Had office 2010 installed and removed with revo uninstaller and was even able to install it a second time with same trial key. But now due to error code 25004 can´t install again and i also uninstalled with office 2010 tool kit which cleans whole registry and the ms fix it for office 2010 and tried all your funny tricks from cleaning registry till pray..... whats else shall i do?
    Wednesday, November 24, 2010 10:39 PM
  • Hi

     

    if you are getting Error 25004  then The product key you entered cannot be used on that machine.  This is most likely due to previous Office 2010 trials being installed. (System error: <hresult>)

     

    The key you are currently trying to install with, is an Office Professional Plus Trial key. A machine will allow one Professional Plus Trial key installed on it ever. Meaning you can install a trial on a machine, used it for some time, uninstall Office. When you go back to the Microsoft website and get a new key, the second installation will be rejected with the above error message.

     

    If this is not how you ran into the situation, please let us know the exact (System error: <hresult>) in the above error message

  • ok guys,I got one for you.I've read almost all of these postings today.I have the same issue,kinda.

    I downloaded microsoft office professional free trial awhile back,then skipped to the student edition when the professional free trial ended.

    I have tried "everything" in my humanly power "know hows" to get rid of the professional edition and it will NOT be deleted from my laptop.any ideas?

    I downloaded the business edition 2 weeks ago after the student free trial edition ended.now here's the thing: after downloading the business edition, it started extracting the items needed for powerpoint,word,excel,etc.i opened up word to test it out to see if it was offically download,it was. 10 mins later i downloaded "visio" free trial for my schooling.when download,visio asked if i wanted to either switch,convert or do soemthing with my all files or something like that? i thought about it,and clicked yes.BIG mistake.My microsoft office business free trial vanished from my laptop.I redownloaded microsoft office business 2010 free trial again 4-7 times there after and every time i do that it will not open or run.i keep getting error reports o send like this one,repeatively.

    C:\DOCUME~1\User\LOCALS~1\Temp\SetupExe(201012051317566C0).log

    i've tried everything to get that free trial back and nothing works.I've done a system restore 5 times,created a new email address when logging into windows for downloading the free trial,tried downloading it from another website other than my schooling website,deleted ANY microsoft office files of any sort on my laptop period,but nothing works.

    people,i would greatly appreciate it someone has the key secret to unistalling the profesisonal edition from my laptop for good and getting the business edition downlaoded back unto my laptop like once before.

    do i need a patch package installed in order to get it back? do i need any other tools to download so i can have the free trial again? i think my laptop picks up on the key product number from the very first business free trial download and won't let me have it again regardless me only having the business edition for 10-30 mins.

    any help,good help will help alot.

  • hello, i have no idea if you can keep parallel installed different trial versions of office. But try the revo uninstaller pro and remove your office professional in extended mode with that program. at least i could install a second time on my netbook without any problems i jus ____ up not uninstalling with revo pro.

  • Hi All,

    Looks like there's alot of struggling users including myself with this issue. I am using windows vista home premium and am having the same issue. I am unable to install office 2010.

    Did anyone get an utlimate solution to this?

    Error 25004. The product key you entered cannot be used on this machine". this is most likely due to previous Office 2010 Trials being installed. (system error: 1073422308).

    I'd love to know...a FIX!

    Thanks

  • I've tried everything. I went from Office 2007 Enterprise (college academic) and bought Office 2010 Home and Student. The installer crashed halfway through and did not shut down properly. I tried again and it worked, until I got to this same error. Now Office 2007 is broken too, so I have no Office at all on my computer, and I am unable to reinstall 2007 or 2010! This is ridiculous! Because I paid to upgrade, I now have NO Office running at all.

  • Hello Matt,

Please contact the costumer service and let us know their solution to this problem cause i searched all on the internet and couldn´t find a solution to this problem and most funny solution was jus to buy it and now we see that even this last solution doesn´t work out lol. So please let us know what  the good Microsoft solution for this problem as soon as possible;)

  • Hi Matt,

     

    Gatinho79 is right, you can get free technical support if you purchased an upgrade. It's people who are trying to install the trail version and getting stuck that a) have no solution b) cant call microsoft for help!

    Why have a trial version when everyone cant trial it?

    The problem seems to occur between 2007 and 2010. Anyone who has installed 07 and then removes it and tries to install office 2010 this problem occurs.

    Argghh!

    Still waiting for a fix! Anyone???

  • Hey guys, I'm working on finding a solution to the installing and re-installing of microsoft office 2010.I recently downloaded the home edition and professional edition.The home edition un-installed w/o any issues whereas the professional wouldn't.I tried everything in my humanly power to the best of computer knowledge i could possibly use,nothing worked.someone on here posted back to my repsonse and said to try revo unistall pro.I downloaded it,for free,and used it.It worked! It unistalled the pro edition like tri was noones business and cleaned up any leftover files belonging to it.Itw as very easy to download,to use,and work with. For anyone wanting to re-try the trial versions again,your best bet is downloading any microsoft office 2010 of any version again is to erase the original downlaod from your computer registry and then try dowloading it.I,however,do not know how to do this,yet.I'm not well equipped or familiar with that area right now.someone mentioned it back to me on here in a post to do this,which is also the same person that advised me to downlaod revo unistall pro to remove the professional edition,and it worked like a charm. Over the past few days I have been trying to redownload any latest version of office whether it's 2007 or 2010.I can go as far as having it doanloaded,but when it up loads or extracts the files,that's where the error keeps popping up "microsoft has encountered an error and needs to close". I downloaded the home edition awhile back but 30 mins after i literally had it on my laptop,i was downloading the free trial for visio for my schooling.While visio was being installed a small rectangle box opened up and aske dme if i either wanted to switch,move or extract files from micrsoft office or something like that.I can't remember exactly what ti asked,but after thinking about it for a mintue,i finall ckicled yes.BIG NO NO! When I did that it completely erased microsoft office from my laptop.2 months worth of free microsoft trial version down the drain in a matter of 20 mintues of usage. I had been trying ever since to get it back,but nothign helped.I even called microsoft for extended help and they simply said to re-dwownload it again,which i did do like 10 times over and over,nothing worked. I've been trying to get it back over the past few days.nothing works.i would like what error it is that it keeps giving me or what the genuine issue is.

  • hi dripper,

     

    i am glad that i could help at least one person, guess i was the revo recommending guy;) but since i didnt remove it withou revo i can´t reinstall it anyways. on the whole web jus one guy says he solved that problem by cleaning up registry with ccleaner. Doesn´t work either for me. Funny is that you called microsoft and they recommended you to redownload again lol. Maybe someone knows somebody working at microsoft and could ask which freaky leftover file is responsible for that error 25004. Like i said even on my desktop pc i never had any trial of office 2010 jus office 2007 and same error 25004 occurs- all too freaky to me cause like we see above even buying the upgrade doesn´t solve this error. Well many thx in advance for the person who finds the solution to this problem.

    best whishes to everybody and a happy new year in advance;)

  • BT Professionalbaki, what are you writing?

    *sigh* Anyone with a solution please? Does anyone have a friend at Microsoft who can bypass their helpdesk and find a solution? Geez.

    This is so frustrating. After doing more research, I think the error comes up has to do with registry issues. I used regcure and it found so many registry issues with my laptop. I'm scared if I fix all it will clean out my laptop and with no backups loose my data.

    Regcure you have to buy too!

    I'll surf around for free registry cleaners and see how it goes!!

    I'm still trying to get office 2010 home and student installed!

  • well final solution cause this all here lasts too long. Jus format your machine cause this works 100% altough i read some statements of guy who stil had the problem and then with office toolkit make a backup so that you can install again when you want and where you want without downloading hundreds of things and wasting time with studying software design writing a tesis about registry entries. Its a shame that a test version can´t be tested cause first great bug comes with installing it!! So again forget all your sandboxing tricks, registry cleaners, manually registry cleaning, office cleaning and fix and uninstall tools, win 7 clean boot and all of that!!!!!!!
