I have been able to get this to work on Vista 32-bit. here is what i did: 1. Uninstall Nero Lite 7.7.5.1 2. Run Nero CleanTools (from Nero Website); you dont have to clean user profile information 3. Install Nero Lite 7.7.5.1 4. Run Nero Lite as Administrator if someone has not installed Nero Lite at all yet, and your system has been freshly formatted (or you have never installed Nero Lite on it), try installing Nero Lite 7.7.5.1 on your system and run the program as administrator to see if it works. Alternativley, if you install Nero 7.7.5.1 with Nero BurnRights, this will bypass the need to runas Administrator scratch that last one, it does not work if you run it with BurnRights, but it does run if you runas Administrator could someone try running it as Administrator that has it installed already with that error message and see if you still get the same error.
