I received the vouch and can confirm that the method is working!
You will receive a step-by-step guide with pictures to help you understand where to download and how to install the software + activate it.
About it being a "ilegal" copy of a method already being sold by someone else, I can't really confirm since this is the first method I'm testing. But it worked as promised, and even my After Effects that was in trial seems to be activated now.
