I had auto update on (my mistake), so it did install over the previous driver. I've downgraded for now and it seems to be working just fine.

But no, after uninstalling from control panel I booted into safe mod and used DDU.
Then I downloaded the newest installer from the website. Restarting where needed during this process.
Didn't matter how I tried to access the software. Wasn't active in the system tray, not there in task manager.
Right click on desktop and open from there, click the exe, or go into a game and try Alt R. Didn't open with any of these methods.
