First of all running setup is just to configure your computer's control system for playing the game. To actually run it you're supposed to be able to just click L3D. Which BTW doesn't work. I also tried running it with the latest version of DOSBox and it said I'm missing something called MSCDEX whatever that is! I even tried the compatability tab bit and that didn't work either surprise, surprise! You sure you uploaded all the guts to it? You maybe didn't leave out a kidney somewhere?
