[Wine] CoGetClassObject errors

[MichaelZ]

I am running the application using Wine (version 0.9.27) on Fedora 4. The application runs fine. But when I try to access API calls from my testing application, it is unsuccessful with following errors:
err:ole:CoGetClassObject class {079aa557-4a18-424a-8eee-e39f0a8d41b9} not registered.

Any idea why? Is this Wine problem or I have missed some steps?
Thanks.
