My nephew's just got an xbox for christmas which includes a download only version of skyrim, but they're having trouble connecting it so I said he could bring it over to mine and use our connection to download it. Problem is, our connection is by no means a good one so it's going to take at least all day.

I'm not sure what the process will be, but is there a way to use my cd version to install onto his hard drive and validate it as his version?

Apologies if this is a stupid question, I've only ever bought games that were install from cd before.
