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.
Is it hard to follow the direction?
IMO no its not most of the time that it takes up is stuff downloading, and everything else is thoroughly explained in the set up guide.
