I recently have been looking at the X3 Series on Steam and I have been really interested in it. Especially when I found out that my dad actually owns TC and Rebirth. He says that he can give me TC but the problem is that it is on a CD and my desktop doesn't have a CD/DVD drive. I normally resolve this by copying the CD files onto my laptop (with disc drive) onto my desktop and then run the install files. But I've heard that TC requires the disc to run.
Is there an updated (as in 2014-15) way of running the game without a disc? I really want to save money by having my dad give it to me rather than buying it off Steam.

Thanks for any help.
