Need help about understanding what is AHK_H and how can i install it correctly!

[Galakrond]

I saw a file being compiled with ahk_h on Youtube. First of all, I try to install ahk_h on my computer for 2-3 hours, but I have not been successful. (Which is driving me crazy)

I have a few questions about ahk_h.

Does the autohotkey version installed on my computer matter to ahk_h?

I'm using version 1.1.34.4 (and I'm happy with it.)

I noticed that when I want to compile a file without ahk_h, my codes appear in the last part with notepad++ (damn).

But when its beign compiled with Ahk_H (Ahk2Exe) its beign what i want to archieve.

I searched SO MUCH on the internet that no one really gave enough information on how to install AHK_H on my computer properly, or with which versions it works. (YES MAYBE IT EXIST BUT NOT FOR THE NEW GUYS IN AHK.)

I NEED A ROADMAP EXPLAINED IN STEP BY STEP WITH VERY (very,very) SIMPLE AND UNDERSTABLE WAY.

Thanks for any help, Seriously.
