Today I reviewed a new beta release of the VFP 9 SP2 Help file being prepared by Francis Faure on VFPX. I needed to compare it to the Help file for VFP 8 and when I tried to access the VFP 8 Help menu pad I got the following error:
OLE error code 0x8002801d: Library not registered.
To be clear, I got this error trying to get the Help menu to drop down inside of Visual FoxPro, not selecting the Help option on the menu, or by pressing the F1 key (which failed to bring up the Help file). Puzzled I ignored it and opened the CHM file directly in Windows Explorer. It opened fine and I was able to provide the feedback to Francis. I rarely use VFP 8 these days. Actually I mostly use it to compare behavior to VFP 9, which was exactly the case this afternoon, or to help other developers when I am mentoring or answer questions on the various forums.
I took a shot in the dark and tried using REGSVR32 to register the FoxPro Help EXE found in the Common Files folder. I found out immediately this was the incorrect approach as REGSVR32 barked at me that it failed. Fortunately the Visual FoxPro Wiki came to the rescue as it does so frequently for me. The correct way to register the FoxPro Help executable is to run the EXE with the /RegServer parameter.
FoxHHelp8.EXE /regserver
You can do this via the Windows Command Window, but if you are running Vista, Windows 7, or an earlier OS without Administrator rights, make sure to run the Command Window with administrator access.
