I am having the same issue of not being able to use my help functions. When
I hit F1 or the blue circle with the question mark I get a microsoft message
window stating "There is a problem with one or more installed help files.
Please repair your Office installation and try again." I tried to repair as
instructed using the Office 2007 cd. This is an upgrade so then when that
did not work I uninstalled both Office 2003 and the 2007 versions. Then
reinstalled both the 2003 and the upgrade. I also run all available updates.
My OS is XP with SP3 installed. Thank you for any advice you can give.
