Download RPG VX Ace from this site: https://www.rpgmakerweb.com/run-time-package
ik but i feel like this is something you shouldn't need to do for a game? Like updating your driver's and stuff sure but downloading a whole extra program seems a little much? Especially since i haven't any idea what this program is or does.
And if you as the player need to download an extra program to play they should tell people in the description aswell so that you're aware beforehand
