I'll be uploading a bug-fixed version shortly which correctly generates 
enums.

Ensure you're initializing COM with CoInitialize. I usually do so in a 
static module ctor, like this:

	module main;

	import com;

	static this() {
		CoInitialize(null);
	}

	static ~this() {
		CoUninitialize();
	}

Hope that helps.
