“64-bit exclusive” is redundant — all x86-64 CPUs from 2003 onward run 64-bit OS.
It reverse-engineers the algorithm that converts a request code (hardware hash) into a valid activation response code. The user enters the installation serial number and product key, then the keygen generates a matching activation code. xf a2012 64bits exclusive
