There have been issues with the Student upgrade, particularly the ones from that website (can’t remember the name), but a new iso has been released that fixes the problem.
Also, this was completely different from the “Upgrade” for $30 – as the kid got a full retail version of Win7 Pro – it came with 2 DVDs, one for 32-bit and one for 64-bit. All for $30.00 – damnit, I should have done it. I thought I was fine, but the DVD I had was only 32-bit. I am trying to get a 64-bit one now, but we will see. You might still want to try calling, if you want full, and not upgrade (if there is in fact any difference).
