Application won't work on my "Version of Windows"

I’ve been a big fan of the RP Concept on GTA ever since the first announcement of it, I finally got my hands on a pc copy of gta so I was able to finally play it, my 3rd day (Today) I get this image and I’ve tried everything, Disabling Anti virus, updating windows, “Trying” to reinstall FiveM, but nothing works, if you reply to this thank you for taking time to help some random guy on the internet.


and yes my copy IS legit.
