Sam, here are just a couple of hints that I always try in similar
curcumstances:

Try CoGetClassObject, with the class id of the com object, and request
IClassFactory interface.

Make sure that you have specified the UUID of the com object, not the
interface - try using CLSIDFromProgID, after you have verified that the Prog
ID is there, and it correctly references the right class id.

look in the registry in HKEY_CLASSES_ROOT\\CLSID to verify that the classid
was registered.

Make sure that the path specified in InProcServer32 (assuming it is a DLL)
is valid and that the account your are running from has proper permissions
on the path.
