I purchased 2 download copies of TI 10 for my PC and laptop. The laptop does not have a CD burner. I have not yet installed TI 10 on the laptop yet. Does the Rescue CD have to be created on the specific computer it is to be used for, or can I burn it on the PC and use it on the laptop and still have the rescue CD function correctly? In short the question is, does the rescue CD have to match the unique serial numbered TI 10 installation? I can't find anything about this in the user manual.
