I'm using InstallShield Express for installing my VFP app. On some machines in our office I get the message that COMCAT.DLL failed to self register. Other machines install just fine. This message will occur even if COMCAT.DLL is not on the disk when the install is done.
Also, even with the message the file does end up in the Windows System folder and the app runs fine. I just don't want the message coming up because I know it's going to cause our customers to call and ask why it's happening.

I was wondering if anyone with InstallShield experience could give me some pointers as to what to try or an explanation of what's going wrong.

Thanks.
