error starting games via Start - Games ; File association

Hi,

when I want to play Microsft Games I click on Start and then Games.
I then get a window with the Microsft games.

However, when I try to run any game at all in that window I get the
following error message in a popup:

X C:\ProgramData\Microsoft\Windows\GameExplorer\{any SID of a game}

"This file does not have a program associated with it for performing this
action; Create an association in the folder options control panel"

I have tried to restore to a previous version via the properties sheet of
this folder, but it did not work.

Please help!

regards,

Robert
