Office assistant trouble

We use Windows XP on most of our systems in the office. One problem which often used to occur was that Office applications used to give the error “The Office Assistant could not be started. Please repair the Assistant by running Office 2000 setup and selecting “Repair Office 2000″.”

The usual solution I used to try was opening task manager and terminating all Office processes. Something always used to stay behind.

However while going through theDailyWTF, I randomly spotted the solution. Apparently having Office 2003 and Office 2000 installed together causes some incompatibility with the Office Assistant DLL. The solution involves downloading a patch.
