Is it not possible to run SW 2015 on bootcamp/Imac with win 7-64bit.. If no. Why

Im running a nice setup with a homebased Imac running Win 7 64bit on bootcamp. On work I still have a HP workstation, and I transfer my license back and forward..

But the SW 2015 installation failed, and the program wont run.... My reseller trying to help me, but maybe the Q is already out there....
