Because I don't understand his question, due to lack of information. I was bascially trying to ask for more information, however, in retrospect, considering the language barrier, my choice of means made about as much sense as Wouter's OP made to me. Sorry.
Wouter, What exactly do you have a problem with? Which games? I'm assuming you mean certain games in MS Live Games for Windows. Was that a download? Was it orginally for Windows 7? Was it actually a purchased product?
Not being familiar with MS Live Games for Windows, and only having a smattering of experience with Windows 8, I need a lot more information as I can't really guess between the few lines of information that you provided.
EDIT: Right, while I'm at it, what did the crash messages say?
EDIT2: I would of course defer to someone who has more experience a) with Windows 8 and b) with MS Live Games for Windows, but since the problem doesn't appear to be being resolved, it looks like people were having as much trouble understanding the problem as me. Hence my jumping in and asking for more information. I might not be able to fix it, but perhaps for someone else, it will 'click' and they will understand what is happening and offer a solution.
EDIT3: Wouter, is
this what you are talking about?
