I get the feeling I'm missing something here but oh well....go
here to download Dosbox. Take the game .zip file, extract it and put it into a new directory in C, for example, C:\oldgames. Then open Dosbox and type mount C C:\oldgames, hit enter, then type C: - then open the folder by typing CD(folder name here). Then run the game .exe. Does that help? I could've just given you a link to an FAQ page.
Like this one. If you have trouble with the Dosbox commands, type "intro" in the prompt and it brings up a list.
