Fix SteamVR installation path
If Steam was installed in a non-default directory, your SteamVR config/log paths may be referring to non-existent directories.
To fix your SteamVR installation path:
Navigate to: …Steam/steamapps/common/SteamVR/bin/win64
Run vrpathreg and fix the paths to the correct drive and directory, or delete the openvr.vrpath file in user/AppData/Local/openvr
