Here is the error I am getting. Anybody know what I need to do to this
component? Do I need to register it? It won't let me regiter it. (see
previous post)

Are you trying to create an ActiveX control? Which one? Have you made sure
that the control is registered on the system using regsvr32.exe or similar
tool?

Did you ever figure this out? I'm having a similar problem. I'm calling some C# code from unmanaged C++; and when I go to CreateInstance(CLSID), I get a "Class not registered" error. My class ID is correct, so I can't figure this out.

Thanks, and good luck.
