Ryzen Master 2 (.0.0.1192) doesn't work.
Error: Ryzen master driver not installed properly.
Had same error with previous version (126.96.36.1999).
Worked once or twice, didn't work again, uininstalled re-installed, worked briefly, didn't work again.
Uninstalled re-installed 10+ times including trying windows troubleshooter: doesn't work.
Funnily enough had similar problems with Asus Aura software recently (software installs but driver (lightingcontrol) not working), only managed to get a very old version to work.
Specs: Ryzen 7 3700X, Prime X470-Pro, 16GB RAM, 1TB nvme, Windows 10 (1903) Pro.
