Answer 3：Hi Kenshei,

A couple of possible options -

Try changing your settings under ControlPanel/Programs/Program Acess & Comp Defaults and also under ControlPanel/Programs/Set your default programs.  Make sure you check the "Allow Access to Program" button for media center.

or-

You also may be able to correct it by editing your registry. First, back up your registry, then go to:

HKEY_CURRENT_USER\Software\Policies\Microsoft\WindowsMediaCenter

If there is a DWORD in it called "MediaCenter" with a value of "1", delete  it. 

REGISTRY DISCLAIMER

Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk.
