I can do this stuff in C# by simply dragging and dropping a dll

Com *is* supported in D. I think it's better to work with
interfaces rather than classes like the Wiki example:
interface MyCOMType : IUknown {}
Then when you get a pointer from CoCreateInstance or whatever,
you cast it to the interface type and away you go.
In your code, your problem is that CoCreateInstance is failing,
not that D doesn't support COM. It will help you to find out what
the actual value of 'hr' is. Possible values are listed at [1].
