itch.io

You gotta right click the file and unzip it with WinRAR

ok so when you download it right extract it from the zip file downloads on your pc and then open steam vr and connect it to ur headset from there you can go to the folder of the game not the zip and run the file that has .exe at the end it should run might take a bit depending on your specs 

Thanks for the the help you both. I didn't have winRAR yet that was my main problem.
