I'm not sure what's going on. Now, I'm getting a similar CoCreateInstance message when running the app, but it says "Access denied" even when I test it directly on the NT machine with the Administrator account!

>I don't know the answer to your problem, but I can tell you it does NOT sound like an impersonation problem. If you are getting the same error message even with the Admin account, there must be something else wrong. Not sure if this helps, but thought I'd throw it in.
