I d/l all 3 parts, extracted them to .ISO files. They all have the same name, size, date. Since they all had the same name, I put 1, 2, 3, each in a separate folder. Got an ISO burner program. Burned "Part 1" to a DVD. Burned part 2 - the ISO erased part 1 and I the same set of files on the DVD...um...

Do I have to install all 3 parts? Or do I install part 1 & set it up, then burn part 2 separately to another disk, and set up that one also, then part 3, etc.? Or will just any one part be sufficient? If they're all the same, why have 3 parts?

As you can see, I'm confused. <--See? Please explain. TIA.
