Is one activation valid on different OS on a dual-booted machine? (No.)Solved

Just to make sure, since TurboActivate uses hardware fingerprint I'd assume that if I have different operating systems (Windows and Linux) on the same pc, dual boot, one activation will allow for using the license on both systems right?

No, the fingerprinting is completely different for every operating system. So dual-booting a machine with 2 different operating systems will require 2 separate activations.
