Thanks so much for this tip! I spent all day today trying to fix an issue on my computer trying to upgrade from Office 2007 to Office 2010. It failed to uninstall Office 2007, so I thought that was the problem. Manually removed Office 2007 because it
wouldn't uninstall normally. Still couldn't install Office 2010. My computer was a Windows XP computer so the location is a little different.
Renamed the "C:\Documents and Settings\All Users\Application Data\Microsoft Help" to "Microsoft Help.old" as you suggested, and the installer for Office 2010 worked! I bet that is all I had to do to get the Office 2007 to uninstall correctly too!
Thanks again for the fix!
Try renaming the ‘Microsoft Help’ folder and then install Office.
Follow the steps given below to rename the Microsoft Help Folder:
1. Click on Start > All Programs > Accessories > Run > Type %Programdata% and Click OK
- Rename the 'Microsoft Help' folder as 'Microsoft Help. OLD'
Now try installing Office and check if it works.
