Yes, I was going to report back here with that. The DEP settings fixed the issue for one guy.

I will also recommend installing the older DirectX DLL for those who did not get it to work yet, we'll see what happens. So far only three users are reporting this issue out of many, so it seems to be an issue more with their setup than with the engine or my script (so it would seem). But if there's anything I can do to provide the right DLLs or alter my script to accommodate their systems, of course I would love to be able to do that.
