Hi all,

I got a problem with Windows 8.1. In order to play MW3 I need .Net frame 4.0 running on my pc. However, 4.5.2 is integrated in Windows 8.1. I can't install 4.0 now because there's already a higher framework installed. I searched and searched and I can't find any solution. Is there a way to manually delete 4.5.2 and install 4.0?
