Ok, I've tried things like uncommenting

and everything crashes with bad reference.

My thinking is that CoCreateinstance is suppose to give us a
pointer to the interface so we can use it, if all this stuff is
crashing does that mean the interface is invalid or not being
assigned properly or is there far more to it than this?
First of all, you can't just comment/uncomment parts of COM
interface descriptions. Each COM interface has some specific
layout of its functions, and if you list them in wrong order or
skip some of them the virtual methods table gets completely
screwed up, so you think you call one method but end up calling
another, because you intended to call method #12 and instead
called method #4. COM interface definitions in D must match their
definitions in IDL exactly. One omission of a method, one mistake
in its type, and you're fucked.
