If you're trying to register the file that begins with "Interop", you're registering the wrong one. You need the original .DLL file that you referenced in your project. Run REGSVR32 on that file and it should be good to go.

BTW: Error 80040154 means that the CLSID cannot be found in the registry. You didn't register the COM class you're trying to use.
