Well, in Ubuntu you can just right-click on the executable icon in Nautilus and select "Open with Wine windows emulator". However, in a terminal window I type "Wine" and give the full pathname (which is in an ext3 Linux partition). The output, apart from the error message, is: err:wgl:X11DRV_GetPixelFormat Unable to find a WineGLPixelFormat for iPixelFormat=0 fixme:wgl:X11DRV_wglChoosePixelFormatARB unused pfAttribFList fixme:wgl:ConvertAttribWGLtoGLX unsupported 2012 WGL Attribute err:wgl:X11DRV_GetPixelFormat Unable to find a WineGLPixelFormat for iPixelFormat=0 fixme:win:SetLayeredWindowAttributes (0x30062,0x8000000f,0,1): stub!
