OpenVR Error! "Log path could not be located (112)"

So, I've been pulling my hair for the last two days and don't know whats wrong. After borrowing my Vive to my sister for a while I got it back and tried using it for my old project. Now I realized that SteamVR had been updated so I could not run it using my outdated code, so I updated the latest Steam plugin but I get problems. After cleaning most of the problems I realized I still have a big one that I cannot get around, the dreaded "Log path could not be located (112)" followed by Virtual Reality SDK OpenVR failed to initialize.

I've tried with different unity version with fresh projects. I've tried the SteamVR 1.25 plugin instead of the new, still same problem. I have reinstalled the driver (changed USB ports) for the Vive and checked that it works for other games still no luck. I've made sure that the OpenVr is installed through the package manager and tried both the 1.0.2 version as well as the 1.0.1 version. Finally I've checked that the OpenVr is added in the edit->Project settings->player and that the Virtual Reality Supported is checked.

I've mostly used the latest version of Unity 2018.3.0f2 but as I said I've tried others. I am using a new computer then when I first made the project and I'm thinking perhaps I'm making a big mistake where I am missing something simple. Do I install OpenVr myself separately? Anyone got any idea? I've googled the S*** out of this and found absolutely nothing.

Well finally fixed it. Apperently the file openvrpaths.vrpath in C:\Users\Username\AppData\Local\openvr\ contained path to my backup drive steam location and not the path to my current drive.

So changing the file to:

{
"config" : [ "G:\\Steam\\config" ],
"external_drivers" : null,
"jsonid" : "vrpathreg",
"log" : [ "G:\\Steam\\logs" ],
"runtime" : [
"G:\\Steam\\steamapps\\common\\SteamVR\\",
"G:\\Steam\\steamapps\\common\\SteamVR"
],
"version" : 1
}

did the trick. Hope this helps someone out there.

 

You're a legend pal. Been struggling with this one for a few days now, worked a treat. Many thanks!!

 

Thanks a lot!but my problem is that when I use chinese to name the exe file,some chinese name cause this error.so,finally,I use english to name my software.

 

What a legend. Dunno how this got messed up but my file had bunch of different paths in it that didnt need to be there. i guess after messing around and moving steamvr app a bunch it just got confused. Deleted the vrpath file and launched steamvr created a new non broken file. ez fix.
