>In my first foray into including OCXs in my application, I get an
>error about comcat.dll. If I use the setup wizard to create an install
>I get the message "xxx.dll was unable to register itself in the system
>registry" when I run the setup on the target machine.
>
>Comcat.dll is coming from Fox, not my ocx's. I tried a newer version
>of comcat.dll to no avail.
>
>I am just starting testing, so the development machine is Win95 and
>the first target was Win95 just to keep it simple (HaHa). I'm using
>VFP5a while I'm waiting for VFP7, hoping to skip 6.
>
>Is there a way to edit setup.inf so it doesn't use the file if the
>user has a comcat.dll already. Any other ideas?
>
>Thanks for any help.
