I've registered myself for a 1 year academic licence for SolidEdge ST7 and i got the licence key by e-mail. Unfortunately my laptop doesnt run the x64. I really need the program to deal with exams, so i downloaded SolidEdge ST6 from the Siemens site to practice with, but the key i got by email doesnt work with ST6. I guess ST7 key doesnt work on ST6, but how do i swap my ST7 key for a ST6 one? Can i do it, and if yes, where?
