Student And Faculty 32-bit Upgrade Version To 64-bit

I recently purchased a copy of Win 7 Ultimate upgrade for Student and Faculty under the Microsoft Student Select program. Unfortunately at the time they did not specify whether it was the 32 bit or the 64-bit version and my understanding was that upgrade version included both 32 and 64 bit versions. When I received it, it was the 32-bit version only. My question is this;

1)Is there a 64-bit version of the Win 7 Ultimate upgrade for student and faculty?

2)Are the product codes interchangeable between the 32/64 bit versions (I read in a thread they were for the retail versions, was not sure this applied to Student and Faculty version)

3)How I can get a hold of the 64-bit version? As the operating of the programme says they only have the 32-bit version.
