Recently I attempted installing Office 2010 on an Windows 7 box. However, on this particular system the installation failed with the warning that:
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.
Clearly the owner had been Beta testing Office 2010. So, I uninstalled the Beta and then tried to re-install the release version… and I received the same error. “No problem,” I thought, firing up The Control Panel. I found one program of the Office Suite that was still there. I uninstalled it and tried once again to install the release version. Same error. (Maybe I should have used good ol’ Revo Uninstaller. http://www.revouninstaller.com/ .) So what was I to do? Dive into the registry searching for all references to the Beta? No thank you!
Microsoft Knowledge Base to the rescue: http://support.microsoft.com/kb/290301 . Microsoft has actually made a tool to solve this exact problem. (Office buggy? no way!) You’ll note that the on screen instructions say to choose “Run” when you click on the tool. I found, however, that I had to save the .msi first in order for it to work. Once it did run successfully, I tried again to install the release version of Office Professional 2010. Bingo! installed without a hitch. One more satisfied customer.
-Remember, your computer should work for you. Enjoy.
P.S. If you want to beta-test software you should look into virtualization, or building a spare computer that doesn’t fulfill a critical role.
