I was trying to backup mercenaries and was following one of the tutorials someone posted. I am running under windows XP and when I try and run the installer I get an error of: (C:\WINDOWS\system32\autoexec.nt. The system file is not suitable for running MS-DOS and Microsoft windows applications. Choose 'close" to terminate the application.) I tried ignore and different compatability modes and no success. I didnt see anyone else here with the problem. Anyone able to help?
