So it's a dll you have control over ?
-
Do you have several calls to CoInitializeEx ?
Are you properly calling CoUninitialize when you're done with your COM stuff ? -

Hi
then use std::cout to show the HRESULT.
It can give hints about why its not loading,.What im a bit puzzled about if that is the same DLL used in the MFC app, and you did not change
the actual DLL code. why should it then stop working? -

"This is a bug in the DLL you are using. A DLL should never call CoInitializeEx() on a thread that it didn't create. "
