gfwl crash after dotnet35 installed
Installed dotnet 3.5 via winetricks (which gave me an error at the end of the installation, as expected), then reran GFWLClient. Received the attached crashlog.
Now you're running into bug http://bugs.winehq.org/show_bug.cgi?id=18640
You could try if disabling d3d9 (under winecfg/library tab) helps
