If the “Error C200 Room Setup is Invalid” message keeps showing up, and games can’t be loaded through it, it is probably caused by conflicts created by something installed in the PC. Check your anti-virus software first. If the problem still exists, uninstall and install the SteamVR, update firmware for all the devices, update graphics driver and restart the computer.
I know its an old post my issue is same but in a different scenario. I face this error when i switch to another user account. Everytime I have to setup the Room to start my game/Application. Is there any way I can avoid this ??
Also other than that anything Steam VR saves user specific ?
