Saving FSX to disk to put on another PC

Since I'm using my dad's computer, he didn't design it for gaming, thus it has no video card. My brother's computer is upstairs, with a decent vid card, but he's on a wireless router and sometimes the connection is finky. So can I take my FSX demo from down here to put it upstairs on my brothers? I'm sure I can, I just don't know which files to put to a CD.
Thanks,
James
