I've extracted the zip, and tried opening the auto updater, but it hasn't done anything. I also tried moving the game into the same folder as the auto installer (along with all the other files) but it hasn't worked. I've even tried moving it into that little folder inside the folder (titled "ref"), but that also hasn't worked. How do I actually open the auto updater?

If you haven't then 1st, download the newest auto updater and then also install .NET 6, which you can get here:https://dotnet.microsoft.com/en-us/download (Get the Runtime, not SDK) Btw the .NET thing i copied from the download I.RULE and the Ruler page so the website should be the thing where you get .NET
