What email did you use for your upgrade? When I upgraded, I had to type in an
email in order to receive a proof of purchase. The email that I put was also
registered to my digital locker. Within the email, their was a link to this
file. I had the option of either running it straight from the link, or saving
it to my desktop for later use. I save it to my desktop for later use, but I
also received a copy of it in my digital locker. You can locate your digital
locker in vista by going to start, control panel, programs, and then "Manage
programs you buy online (digital locker)". Your whole purchase revolves
around the email that you put, when you made your purchase. Microsoft claims
that you receive a copy of your license in your digital locker 3 days after
purchase. I actually received it about 2 weeks later or so. I hope this helps
some.
