First question is what version win7 are you using? Plus have you tried turning off the UAC? Then there is a thing about compatibilty... go to C:\Program Files\Stardock\Object Desktop\LogonStudio and right click the Logon Studio Vista.exe file and select the troubleshoot the compatibilty. See what it says and follow the instructions for setting the program to run. That may or may not fix your problem unless there is a issue with another security program.
