After trying all options mentioned above
Try This
I've done it with winimage(use any alternative) and Virtual CD (ver.7)
1.> First make an iso image of your CD with winimage. yes it will not get done. (do not delete the incomplete image, it has all the structure/info. needed to create virtual cd of protected CD's)
2.> now insert this image using Virtual CD in your virtual Drive.
3.> Create Virtual CD of the Inserted Incomplete image. (Allow Virtual Cd as Source for this option in Virtual Cd settings)
4.> now edit the created virtual cd using the virtual CD editor. (Open .vc4 file for editting)
5.> now copy your cd to any folder in HDD
5.> copy all files to the editing virtual cd (replacing all existing files)
6.> Then Create virtual cd from the editor itself.
Thats it. this method will save your existing Genuine CD from gettin Scratchs
I've successfully created virtual cd of Dungeon Seige, Mech Warrior (get with my HCL PC) and DukeNukem Project Manhettan usin this method.
