For some games on itch once I download nothing shows up as well. You have to delete the files and empty the recycle bin. Once done redownload and try to extract again. once you do extract, click on the fill and click on the application. A blue box should pop up saying that windows stopped it from running due to a possible security risk. Click more info and press run anyways. Hope it works! If it doesn't, try to reinstall one more time. I'm sorry if it doesn't help
