Try looking at the source to win32com.client.Dispatch, and see how it first
tries GetActiveObject() - try just calling CoCreateInstance() without the
check for GetActiveObject.

If that doesn't work, I'm afraid you are probably SOL - it would be the
object itself implementing these semantics and therefore hard to defeat.
