Unity beta 5.4.0f2 "OpenVR failed initialization "

Hi there!

I get this error message every time I open Unity with Virtual Reality enabled

I'm using Unity beta 5.4.0f2 (Unity Free)

I works with a DK2 and Oculus enabled, but not with a Vive and OpenVR.
I saw this post on the steampowered forums about restarting SteamVR, but the problem persist anyhow.
Any ideas?

Thanks!
Lasse

 

Thanks for the reply! Yes it happens even in an empty project. It happens if the Virtual Reality function is enabled. I just tried reinstalling SteamVR but the problem persists. Its not a huge problem for me since I mostly rely on a Oculus DK2 to work, but I'm sure some other people will run into the issue as well.

 

Hi,
I have exactly the same error after having deleted the SteamVR folder (idk if had the error even with it). Any clues to make this message disappear ? I only wanted to uninstall the SteamVR asset..

Editor Log:
Compositor failed to initialize.Compositor failed to initialize.VR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!
(Filename: C:/buildslave/unity/build/Runtime/VR/openvr/OpenVR.cpp Line: 293)

 

The path registry gets set up the first time you launch SteamVR. A) Make sure you have installed SteamVR through Steam and launched it at least once from there. B) If you have since moved where SteamVR gets installed, if you manually launch it again via Steam the registry should get updated to point to the new location. C) If all else fails, you can manually reset the path registry by browsing to where you've installed SteamVR and running bin/win32/vrpathreg.exe sethere

 

Oh, also there was a bug in the first version of openvr_api.dll that was shipped with Unity that didn't handle some unicode characters in user names properly. You can try replacing it with the latest from github here: https://github.com/ValveSoftware/openvr/tree/master/bin

Note, this only applies to Unity 5.4 - if you are using an earlier version of Unity then you should use the version that ships with the latest plugin here: https://www.assetstore.unity3d.com/en/#!/content/32647

 

Hey aleiby!
I was unable to locate the vrpathreg.exe. IÍt should be in the steam folder, yes?

I tried replacing the .dll but with no luck.

 

This is a separate issue but somewhat related. 5.4.0f3, OpenVR Missing from Build?
OpenVR isn't even in the list, but it shows this when I import steamVR.

 

everyone have solved the problem?
i have the same problem:
VR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!

everyone can help me?
(i work on windows not on mac)

 

hello，
have solved the problem? thank you !!! i have the same problem !

 

Hello all.I am just a beginner.I have a question please answer me.How can I add openVR SDK in unity.

 

Has anyone yet resolved this issue?

XR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!

 

Just figured out how to get rid of this pesky error. In my case I just had to add the Mock HMD - Vive SDK to the SDK list

 

Where do I find the SDK list? I have a new empty project with the [CameraRig] prefab dragged and dropped in the scene to replace the default MainCamera.

 

It's located within the Player Settings, under XR Settings.

 

Ok I am getting this error in 2017.4.1f1 I am trying to build some Oculus OVR SDK project. Here is the thing if I turn on all the logging, and I look at the info warn and error it seems Unity tried to turn on VR SDk Oculus first, which failed. Then it tried to enable cardboard as a back up, unfortunately cardboard is not supported in Editor Mode. So then it tried to run openVR, which also failed because of the Installation path could not be located thing.
Unity v2017.4.1f1, Oculus Utilities v1.25.1, OVRPlugin v1.25.0, SDK v0.0.0.
UnityEngine.Debug:Log(Object)
OVRManager:Awake() (at Assets/Oculus/VR/Scripts/OVRManager.cs:904)

So now I tried re install of OVR Plugin from the Asset Store.

I will post the results.

 

Ok update - so I had to restore from back up. Something in the OVR import breaks this with my version 2017.4.1. Likely Oculus will ask that I upgrade to the latest Unity version and then see if everything plays nice together.

 

I have same problem but using Oculus "VR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!" I don't know how to solve it

 

anybody figure this out, i have the same problem today Sept 2018

 

Vuforia Unity 2018 f1 i have the same problem today

 

I have the same problem, any solution????

 

The problem: "VR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!"

Was solved for me! after importing "VR Sample" On unity assetstore

 

In case this is the issue with someone else. It's necessary to install Steam and then install SteamVR through Steam and then download the SteamVR plugin from the asset store. It says so in the asset's descriptions but it's easy to miss.

 

Does anyone find solution for the same above error
Error: XR: OpenVR Error! OpenVR failed initialization with error code VRInitError_Init_PathRegistryNotFound: "Installation path could not be located (110)"!

I am using Unity 2017.4.11f1.
I have taken complete new project, and imported only "OculusUtilities" and "OculusSamplerFramework".
I have dragged only "OVRCameraRig" prefab into Hierarchy window.

any solution????

 

It works for me thanks Keyserjaya99.

 

Ok so I have been hunting this down for a while now. It seems that the solution is to add the None Virtual Reality SDK. Then rebuild and it should work.

 

I don't know why... but this solution worked for me too.

I'd been working on a project for ages. Never did any updates. Then, one day, the error appeared. I don't understand what caused it, but adding "None" fixed it.

 

It is necessary to have steam open when you launch the build. Also as stated from another thread:

"It's necessary to install Steam and then install SteamVR through Steam and then download the SteamVR plugin from the asset store. It says so in the asset's descriptions but it's easy to miss."

That and having "none" and "Mock HMD" on the SDK box in XR settings
(located in file - build settings - player settings - XR settings - Virtual Reality SDKs)

 

When I enable the main camera, I don't get the error. So it might be about the camera removal.

 

I'm getting this error "Virtual Reality SDK Oculus failed to initialize. Will attempt to enable None instead. " and I am not able to find "VR SAMPLES" in asset store what is the exact name
