My nephew installed his MS Office Ultimate 2007 a while back for some school work, and didn't uninstall it when he went back home (out of state).
When I tried ADD/REMOVE programs it said there was a problem and the program should be re installed... So I decided to try to delete it manually and got rid of most of it (safe mode) then followed MS article kb928218 to get rid of more of it, and could not get rid of any of the GrooveXXX.dlls. Says access denied; make sure disk is not full or write protected.
Figured I could live with these files being left on the drive. But now after a reboot, when I click on (shortcut to) C:, ms updates, windows catalog (and more I'm sure), Office 2007 starts to install! I've canceled it each time, but the deleted Office12 folder is back, full of files.
I have MS Office Diagnostics Service and Office Source Engine disabled in services and GrooveMonitor disabled in startup.
MS Office ultimate 2007 is still in the add or remove programs, though there is no change/remove button. Office doesn't show up in the Glary uninstall manager... shows up in ccleaner uninstall, but doesn't uninstall.
