I don't think it's available on DVD ( ?? ). If you D/L from
Direct2Drive here is a paragraph from them:........Your purchase stays in our records, so you can download and re-install your digital products anytime in the event of a hard drive crash. Of course, you can always back up your download to a CD as well - each time you activate them the first time, our digital-rights management server will check the number of active licenses you have (the number of copies you are allowed to run at the same time.) Don't worry - if you ever have any trouble activating your license or downloading your products again, our customer support team is always here to help you out.

So go ahead and give it a try to the CD.
