Uninstall Office 2010 Technical Preview (Mondo)
Apparently I’m not the only one who checked out Office 2k10 Technical Preview (Mondo) and was then unable to uninstall it. When trying to remove with Add/Remove Programs, I would just get an error that it was corrupt, and I had to re-install from the CD or file. Re-installation did nothing to fix the problem, but a bit of searching turned up this little gem in a help forum:
To uninstall Office 2010 14.0.4302.1000 if you have an uninstall error message “This product installation has been corrupted”.
The Problem is a missing file in the installation folder of office 2010. Office 2010 has an Setup Controller directory and uses the directory to check the installed components. please check the directory “C:\Program Files\Common Files\Microsoft Shared\OFFICE14\Office Setup Controller\Groove.en-us\”. if you have no “Setup.xml” file there please copy the file from the “Groove.en-us” directory of the source files to this directory and test the uninstallation again.
Many thanks to Vikas Narula at http://social.technet.microsoft.com/ for the amazing fix.
