If you don't want to insert your ORIGINAL-DVD all the time, you can use the Game Starter of "GameJack 5". Or you can create an IMAGE of the DVD with that program and then just put it into the Virtual Drive.
I am using the "Game Starter-Function". It works fine with the ORIGINAL EXE. You DO NOT need a NO-DVD-CRACK!
You can find "GameJack 5 (Version 5.0.3.3)" here:
