------- Additional Comments From ehoover@mines.edu 2007-29-07 19:29 ------- In response to Comment #7: It is possible that you do not have Wine fully configured, try running wineprefixcreate. It's also possible you're missing one of the DirectX 9.0 extensions, I have two on my system: d3dx9_29.dll and d3dx9_31.dll. I do not remember if Supreme Commander requires these or it was something else that I installed. If you launch the game at the command line it should tell you which DLL files you are missing.
