Nevermind I got it working.
Would you mind elaborating how you got it to work. There may be some people out there whom experienced what you did and could not get it to work.
Sure. Well I downloaded the game from GOG.com on Opera. Then I went on “Computer” (Yours might be called “My Computer” but mine is just called “Computer”.) Anyways I went on “Computer and in the “HP C:)” drive I made a new folder called “Duke NukemGOG”. Then on the Windows Start search engine I typed “setup” then “setup_duke3d.exe” came up as one of the results. I clicked on that then downloaded the game to the “Duke NukemGOG” folder. Then I downloaded eduke32 coped the eduke32 files to “Duke NukemGOG” folder or whatever file you named your Duke Nukem directory. Clicked on the eduke icon. And that’s that. I have Windows Vista BTW.
