That's odd. On the PC you shouldn't have to install anything, just unzip the files into a directory and run the game program from there (Cuddle Kobold Just A Bite.exe or something like that.) Or are you trying to install on a Quest?
Oh! This is Cuddle Kobold's listing. There isn't anything to download here yet. Go to Just a Bite's listing (listed in the description) and you'll find the downloads there. I'm not sure what's even offering to let you download something on this page, is it the GOG Galaxy client offering it?
