7Loader by orbit30 is available in the VIP section at win7vista.com. It will be available to everyone very soon.
You probably got the version which requires SLIC 2.1. The latest release works on non-SLIC systems as well. Or have you got that one too?
Many thanks, Maher. You've been a fount of wisdom today. You're the one that got me looking in the right direction. Much appreciated.
