10.1 EVA number on 10.2

I obtained a copy of 10.1 form my professor. After typing in the EVA code it looked as if I was able to download 10.2. I have now downloaded it. However it is not working do to a linense problem. It never prompted me to check single use at the end of installing and when i got to ArcGis Administrator and choose the Desktop folder the licensing options are greyed out and unselectable.

Does a 10.1 EVA code work on 10.2? if so how can I get it to work?
