This is a problem with itch.io, not your project, but I can't download it. Could you set your file to be "For windows"?
EDIT: This is because downloads on the website fail for me if they're too large, and itch.io doesn't recognise this file as a "compatable version" though the desktop app (which I installed in the past to fix the last problem with something else). I have sent a report to itch staff, and they haven't responded.
EDIT2: "fail", not "file".
