Good catch.
That’s my first go to when SteamVR misbehaves. SVR files have corrupted more than once on me (especially on updates) and my internet line quality is A+.
Running Steam as an administrator can solve this problem:
Go to the folder with Steam installed (often C: \ Program Files (x86) \ Steam);
Right-click Steam.exe;
Select Properties;
Go to the “Compatibility” tab;
Check the box “Run this program as administrator”.
… same here: i have to reboot to get steam vr to work!
(drivers, etc. all updated!)
“run as admin” or “Steam Library Folders > Right click > Repair” has no effect.
My steam behaves like this: I can start 1x steamVR after booting, then not anymore. But it works by going directly to a vr program like fpsVR and starting it.
I am on old pitool 180 because of backlight setting.
