I have the original on CD-rom and this works fine on Vista, though I have not tried running it on Win7 or 8. This is a cool game with hidden depths, witch I found out just yesterday (yeah, this game is so cool I still play it on occasion), the thing I (re)discovered yesterday is that enemy output of units depends on the number of production derricks they have running on that production facility. This can be used to reduce enemy production to a level where you can easily keep them at bay and at the same time safely collect the wreckage of those units, to build a healthy energy reserve for when you really need it (because you will need it...) Cool graphics, adequate story, cool gameplay, cool vehicles of various features, and the character chips are a nice touch, cool menu music (personally I prefer to mute in-game music..). Somewhat clunky ordering system compared to games today, Ransom will try to get himself killed - keep him on a tight leash, watch your units as they not always will move/position themselves as you planned. If you haven't tried this one, it's a real steal here at gog.com so don't miss out.
