Vortex won't start, says the NET desktop runtime 6 is missing

Installed the runtime twice straight from Microsoft and rebooted, Vortex still says it isn't installed correctly and then closes. Windows 11. Anyone sorted this?

You need the .NET 6 Desktop Runtime specifically, x64, from Microsoft's .NET download page. Not the plain .NET Runtime and not the ASP.NET one, people grab the wrong one all the time. Having .NET 7 or 8 installed doesn't cover it, they sit side by side and Vortex looks for 6. Reboot after installing and it should open.
