--- Comment #20 from frozencow@gmail.com 2011-05-16 08:03:42 CDT --- Sorry for double posting. I just tried copying files from C:\Windows\Microsoft.NET\Framework of an Windows XP installation (which has .NET Framework 4 installed) to wine's installation. However I still got the same message about machine.config and the error loading System.Drawing.
