Shame about the switch. Its worth keeping it in as its probably best practice.

Its not clear what is not working. Is it just touchPC? If so did it ever work? Are you running it as Admin - right click, run as admin from an admin account. I never had much success on coup,e of times i tried it unless i relaxed pretty much all protection to run it.
