What version of windows do you have? It should definitely work on 10 and 11, though I don't see why it wouldn't work on older ones. Are you sure it wasn't your windows firewall complaining, which is very likely to happen (I have explained this in the download instructions). If you are still running into trouble, you could join the Discord and message me there. Maybe I can help
