I created 2 VFP COM DLL's

I included them in a VFP app and built an InstallShield
setup. I ran the setup and all worked fine.

Then later on I changed the DLL classes from a Visual Class
Libraries to PRG's, so I could take advantage of _COMARRAY
and HELPString.

Now when I run the setup, I get an error:

"Error 1911. Could not register type library for file
c:\mydll.dll. Contact your support personnel"

Anyone know whats going on here?

Many thanks
