Can't get Vortex to install via steam tinker launch

I'm trying to install vortext using steam tinker launch git, I have installed it via protonupQT and selected steam tinker launch as the compability tool, every time I click to install vortex it gets the the point of running the vortex installer and I get an error pop up saying something about it only working correctly on windows 10, and than if I click ignore it says it requires windows 7.
