Where can I find the zip version? I can only find the rar file which doesn't work on my computer
you'll have to install an unzipper like 7-Zip, I'd recommend following this tutorial here: https://www.hellotech.com/guide/for/how-to-open-rar-files-mac-windows-10 and that should be able to unpack a rar file into a regular folder for you :3
