    Download Ultimate Windows Tweaker, and under Security tab, check under Windows Applications restrictions. Ensure "Disable Windows Media Center" is unchecked. Apply > OK.

    Hope that helps

    Users receive a message that says "Windows cannot open this program because it has been prevented by a software restriction policy. For more information, open Event Viewer or contact your system administrator." Or, on the command line, a message says "The system cannot execute the specified program."

    The default security level (or a rule) was created so that the software program is set as Disallowed, and as a result it will not start.

    Solution: Look in the event log for an in-depth description of the message. The event log message indicates what software program is set as Disallowed and what rule is applied to the program.

    Got that, looks like my registry was locked. But using the tweaker and applying the tweak helped. Thank you all for replying.
