in reply both of us are administrators (had some problems with the registry in my sisters account that was solved by switching it to admin rights.) as I stated the problem only happens on her user profile. the key went in fine and registered fine on my profile. I believe that it is a problem with the registry on her profile (yes they are different. I know this by installing software to only use my profile (some do), then looking for it in the registry on my profile, then doing the same on the other profile and it does not appear on the other profile). does anyone know what key in the resistry stores the license key. I belive if I enter the key into the registry on my sisters profile the problem will go away. there are no spefic user accounts such as one for game playing, one for internet and so on.
