>We ran into this before, too. We could open the CHM file because HTML Help was installed correctly. However, we couldn't run the CHM file from FoxPro because the FoxPro HTML Help interface wasn't installed correctly. The two files needed are FOXHHELP.EXE and FOXHHELPPS.DLL. I think someone posted the MS Knowledge Base article elsewhere in this thread.

Sure, that's a possible problem too. I wanted to point out the issue with where the CHM file is, because it's not documented AFAIK (I did search the KB), and it seems like it could be a likely problem.
