Im pretty sure you can.

Even if you cant, the game doesnt really "install" like others. It doesnt write to the registry at all as far as I know. Many people just copy the game after installed to a disc. It can be played off the disc. Or even off of a thumb drive.

But one important point. If you order the hard disc and just wait abit instead of the download you get all 3 versions on the CD. Windows and Mac and Linux. Plus a 300 page manual in a spiral binding (it can lay open flat)
