Will not install. DVD problem?

[Kitsie]

I have a Lightscribe DVD and when I try to install Witcher it always gives an error: Data2.cab: (cyclic redundancy check). I heard a rumor that this is because of the optical writer on my DVD and that Read-Only DVD's do not have a problem. In fact I tried installing the game on a laptop with a DVD-ROM and as far as I let it go it installed those files very smoothly. With almost every modern computer having a RW DVD this is a very big glitch on the part of the developers! Too many of the new RPG's need the gamer to buy more hardware to play the game!

Does anyone have a fix that does not involve buying a new (old) DVD?

I doubt you can fix that error. By the way, can you read other discs on your current DVD drive? Because if it's the DVD drive problem, you'd better get a new one.
