I have been trying to install the Games for Windows Client under Windows 8/Parallels 8 (most recent update) and the installation keeps failing with an error code (0x800b0003). I have tried everything suggested in the various Windows/xBox Live forums and nothing they suggest works. And others have had no issues installing this (it is how you install the Games for Windows Marketplace) under Windows 8. So all I can think of is that it has something that Parallels is interfering with. Anyone tried successfully to install this? Thanks,
