Ive downloaded twitch to play a modpack with my friends, but it says i dont have minecraft. i click the faded icon and it says i have a few things missing so i click install, it brings up a loading thing for less than half a second and then goes back to the click install screen. Ive changed the directory to everything, C:, .minecraft, Appdata, everything. Nothing works. i dont know why this is a thing, and i hope that twitch makes there app better for people, because right now its pretty shit.
