The original 3-disc CSI game is hard to get working, so don't feel too bad. If you can, get the 2-disc set (same game but updated). But the game is still hard to work with because it uses an older version of QuickTime.
Does the installation abort after the 99% and erase itself or does it leave most of the install behind?
If it leaves something installed, you could try the
***patch***?
If it's just deleting itself because it can't find a file that's supposed to be on the CD, it sounds like a bad disc set to me and I'd send it back.
