Okay, I don't see a download link at all, as these games are (as I suspected) supposed to be played inside a browser.
What I see is "Adobe Flash is required to run this project in the browser. Enable Flash".
Now since Flash has been deprecated I never bothered to even try to install it at all, and it's not even fruitful to get this to work, since Flash will finally die in 2020. I don't know if itch.io has any plans to make the .swf files downloadable (doing so could violate copyrights of the game's developers, so they gotta be careful on that one), but given the way these games have been uploaded here, and that Flash is going to die, that these games will die with it. The Microsoft browsers (IE and Edge) already stopped Flash support or will do so this year.
I'm very very sorry... But if this a fault on your computer I don't think you'll find much support, and if this is a bug in itch.io, I don't think it's in the site's interest anymore to get it fixed.
