When clicking on a "help" link in the right-hand panel of the help screen, Excel launches itself and tries to open the clicked-on subject—with limited success. This behavior occurs throughout the suite, Word, Excel, &c. In addition, this doesn't happen for every subject, just most of them



The problem first made itself known to me about a month ago. I've been using this software for almost a year without this happening.

I'm using 32-bit Office 2010 running under 64-bit Windows 7 Pro.

Any help will be greatly appreciated.
