I can't install Office 2010 RTM due to "upgrading from a prerelease version"...

    Question

  • I have completely uninstalled the Office 2010 beta and all remaining Office 2007 products, rebooted several times, but the 2010 RTM won't let me install. It displays the following error:

    Setup is unable to proceed due to the following error(s):
    Microsoft Office 2010 does not support upgrading from a prerelease version of Microsoft Office 2010. You must first install any prerelease versions of Microsoft Office 2010 products and associated technologies. Correct the issue(s) listed above and re-run setup.

    The problem is, it doesn't tell me which programs need to be uninstalled to satisfy the requirement. Like I said, I think I've uninstalled everything Office-related, even the add-ins, such as Outlook Social Connector, etc. Any ideas? Thanks!

  • You can try to completely uninstall the Office programs, 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 2010 beta 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 the “Start” peal, in the Search box, type "regedit" (without the quotation marks) and press Enter.

     

    Note: If you are using Windows XP, 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"

     

    9. Click Start, in the Search box, type "%Temp%" (without the quotation marks) and press Enter.

     

    Note: If you are using Windows XP, 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.

    It always a good idea to backup data files before making changes.
     
    Here is the Windows 7 - Vista location for the .pst file
     
    C:\Users\<UserAccount Name>\Documents\Outlook Files
     
    You can also reach it by Outlook Account Settings - Data Files

  • Make sure that the Microsoft Office Outlook Hotmail Connector (Beta) is uninstalled too. This is a separate application so it will need to be uninstalled separately. When I did this the problem went away. If the problem continues you should read this Microsoft Knowledge Base article: http://support.microsoft.com/kb/290301

  • Dear proffessionals - pleeease help!

    I've got the similar trouble....At the beginning the situation was just the same as gregsedwards  had. 

    ( Setup is unable to proceed due to the following error(s):
    Microsoft Office 2010 does not support upgrading from a prerelease version of Microsoft Office 2010. You must first install any prerelease versions of Microsoft Office 2010 products and associated technologies. Correct the issue(s) listed above and re-run setup.)

     After following all your recommendations given to gregsedwards the installation started.BUT on the 3-th step loading suddenly stopps - and appears a message which told that there is a problem with downloading Trial virsion of Microsoft Office 2010 and advised me to contact Microsoft service . I tried to make the installation with "click-2-run" and with the usual way (32-bits)...

    Please help! (And sorry for my poor English)
