I've never bought a game from here. I just want to support a comic artist I like, so I bought Starfighter: Eclipse. I go to unzip it....and then what? I cannot download the itch.io app. It shows up as a virus. I just want to play the game I bought, but I can't seem to figure out how to install it. I actually downloaded it and unzipped it a few days ago and it seems to have completely disappeared off of my computer.....
