The Turrican II game I got from a guy I found selling a bunch of older PC games and I was lucky to get the game very cheap (and 7 other games) and its new condition too
I could not install the game either at first, messed around in dosbox until it worked but dont remember exactly what I did now. But the install files on HD are only a few kb so if you want I can upload the setup files so your game should think its installed already.
