When I download it, it only comes in one file. No extractions. And I can't play because it keeps telling me to "choose to open with this app" but I don't have it.
So it should be, this is a zip file, right-click and unzip it
That's the thing. It comes in one file. There is nothing to unzip. It comes as a .rar file.
Yes, and you can unzip .rar just like you can unzip .zip
