I'm interested in purchasing Microsoft Plus! SuperPack.  After searching and searching i have finally found a seller.  On the product description it says "License: 1 user".  Does that mean i can only download the upgrade on one computer?  Or can i download it on many computers?  If any one knows ... please tell me.  One upgraded computer will make the others feel jealous.  You know how it goes ...

Thanks for your time.
