The uploaded file on here is for Windows only, for the purpose of clarity we will say it typically won't run on Mac. Unfortunately there is no legal obligation for Innersloth to refund you.
However, I recommend you research this as it could very possibly solve your problem. This is the method that I would strongly advise. It means you can run Windows side-along with MacOS on your laptop.
Another much more complicated path is to use a Virtual-Machine which would probably cost more money.
The final other option is to use wine which if you were to choose, I would recommend following these steps for installation. It is a much more complicated process that will be laggier but most probably save a large amount of storage.
TLDR: It won't work on windows, you need to either use a Virtual Machine, Wine or Boot Camp. I would strongly advise to still read my entire comment.
Hope this helps. If you have any further questions feel free to reply or DM me on discord at "Monstr#6218".
