I've been reading over D's com and can't find anything useful.
It seems there are different ways:
http://www.lunesu.com/uploads/ModernCOMProgramminginD.pdf
which is of no help and requires an idl file, which I don't
have.
Then theres this

which is also of no help:

Maybe my CLSID's are wrong. Got them from the registry. The
exception triggers each time. Even if it worked, I wouldn't
know how to use it.
I can do this stuff in C# by simply dragging and dropping a dll
into the references and it works fine but is a bit slow. I was
hoping I could speed things up using D but it seems like COM
isn't really supported, despite what several references say.
COM is supported in D. The difference is that C# hides all the
plumbing behind nice classes.
You're going to need Photoshop's COM interface to do anything
with it. If you don't have a C header that you can translate into
D, you could use a tool included in the Windows SDK called
OleView. It will peek inside COM libraries and give you the
interface definitions.
As to why CoCreateInstance isn't working, make sure you're
calling CoInitialize or CoInitializeEx beforehand. If it's still
failing, use std.windows.syserror.sysErrorString(hr) to see if it
gives you a reason. Otherwise, CLSCTX_ALL might be the culprit -
try using CLSCTX_SERVER instead.
