Anytime I attempt to launch Windows Media Center or Media Center Extender I receive the following popup error:-
“Windows cannot open this program because it has been prevented by a software restriction policy. For more information contact your system administrator.”
Why it is happening:-
If the program under ” set access and computer defaults” is disabled it may happen.
Enable the Windows Media Center in ‘set program access and defaults’ under Control Panel\Programs\Default Programs.Restart Windows Media Center.
