I have an end-user that was having some system problems. She was setup and using IE7 under Windows XP SP2. In order to resolve the system problems she was having, I ran the OS repair by booting from the Windows XP cd. All seem to go fine, but when she logged in and tried to access the browser she received "The requested lookup key was not found in any active activation context." I then removed Internet Explorer from Windows System Components, rebooted and then re-enabled Internet Explorer. I still got the same message but now running under IE 6 under her logon name. I logon as myself and it comes up with IE7. Either way I still get the same message. Any ideas how to resolve?
