I am using Windows 7 PC and have local administrator rights on this PC. Recently, when I right-click an icon in Windows Explorer and select Run as Administrator nothing happens. No window is opened at all, and I see no process being started using Process Explorer. I also get the same behavior when using the Ctrl+Shift+Enter keys in the Start menu’s search box, as suggested at HowToGeek. What could the problem be?

Running program with administrator privileges requires the Application Information service. If that service is not running, then you can no longer run things with admin privileges, and worse, you cannot even start it. Check the services snap-in (services.msc) and make sure that it is not disabled or stopped. If it is, then set it to Manual and reboot.

Does double clicking directly work? If not, there may be something wrong with the program you are trying to launch. Alternatively, you can try typing command prompt in start menu and try start command prompt as admin.

The app launches without admin privileges if I double click. I can't launch cmd prompt with admin prileges either. –  C. Ross Sep 12 '12 at 11:20

  1. Make sure that the service "Secondary Login" is enabled and set to start automatically, and that it is started.

  2. Download this link and run it. It is from symantec and makes sure that .exe files are setup properly in the registry to run.
