I think they generate wrapper code from the typelib. So the wrapper uses
invoke but the user doesn't.

Strange problem.
Here is an idea:

COM objects implement the IDispatch interface as they choose.
It could be that the Excel implementation is more tolerant towards different
types than the MDM object.

I think the MDM objects uses the Microsoft ATL standard implementation (99%
of all new C++ based COM objects do that).
