This application is used to install mods for each game (there are three pre-defined games) without having to do anything. You open the .exe, select the game, wait, and voila, the mods are installed without having to do anything.
IMPORTANT If your games are from M4CKD0GE REPACKS (with online from online-fix.me) and you install mods, if you want online access, you must copy certain files back to the game's root folder: ./game (M4CKD0GE REPACKS)/
