I also tried calling it from the shell using: wine /data/glwin/main.exe I also tried calling it from a linked directory in the wine folder wine /home/user05/.wine/drive_c/glwin/main.exe All gave me the same error... although from the desktop I don't see the actual error codes. if I copy the entire application folder to lets say a local folder using cp /data/glwin /data/local_glwin then run it using wine /data/local_glwin/main.exe it works fine.[/b]
