Answer 1

My first thought would be to make sure all dlls are registered.

Answer 2

Assuming the ActiveX DLL is VB6 and you have access to the VB6 IDE, ensure the class's Instancing property is set to Multiuse.

Answer 3

Use OLE View (comes with visual studio) to browse ther TypeLib entry and check it has the correct GUID and that there is onely one registration. Can you create an object instance from the DLL with CreateObject? If not it is not registered correctly.
