Adobe products/Gen-P

I tried downloading After Effects specifically and it comes with Gen-P. I know someone posted about it but the forum post didn't actually explain how to install it. I've used a keygen before but never this. I tried to google it and even though the reddit group and discord have been deleted I found a youtube video that sort of explains it but it doesn't make sense if you are also downloading the actual program file as well from here, it says to download from creative cloud, so I'm not sure if this is actually the same thing.

But this leads me to a bigger problem. It has you creating an adobe account to download the stuff from CC off the official site. I don't have issue with that, but what if you actually legally own a copy of an Adobe product? Will it be able to connect that you have a version that is not? Because I definitely wouldn't think downloading CC with the Adobe account I use would make sense but I don't know if you can even log into two. Honestly I hate subscriptions and if you could just get a month at a time I would just get the damn thing but I can not afford a year of another program.
