Hello Al ex! Thank you for answering. It worked 🙂
I am not being able to get the GOG-Version to run like QuillsPen described. Could you be more specific how to do it exactly? What do I have to change exactly in the “game.ins-file”? I have the game.gog mounted as drive D (cd rom) and the installed files on hdd as drive C. I can manage to start the Game from drive C, but the “insert CD error is there”. Thank you for the help…
