After reading your suggested page, it does appear that the problem is a security feature that I will have to live with since the CDs will be running on borrowed computers.
BUT, if the same R-folder is loaded from a USB Flash Drive, rather than a CD, the help files work just fine. So perhaps there is another way. Any other ideas?

This sounds like a Windows security feature, because .CHM is a risky format. There's a page here http://support.microsoft.com/kb/896054 that tells you how to turn it off. Alternatively, you can choose one of the other help formats in R besides CHM help.
