    Hey! So I really don't know anything about programming, but (with help) I managed to create software in Unity to work with the Hololens. Small problem though, it does not want to build, because of the following error:

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

    I have tried to use a different Unity version, and I have tried using the Holotoolkit instead of the Mixed Reality Toolkit, but unfortunately that did not help. If I google it I only get references to Steam VR, which is weird, as (for as far as I understood it), I don't need Steam if I am developing for the Hololens. Has anyone seen this error before and knows how to solve it? The software does run perfectly well when I run it in the Game mode in Unity itself.

    Thanks for helping!

    Which SDK's do you have enabled in the XR Settings? You are correct you don't need Steam to develop for Hololens.

    Only Windows Holografic is added to the SDK list in the player settings, I have tried removing this and adding it again, it didn't work..

    Try changing your build target to PC, Mac, & Linux Standalone and look at the Player Settings there. If you have VR Support enabled and OpenVR in the SDK list, it might be affecting your build in the Editor.

    That solved it for me. But makes no sense imo.

    Why if I have UWP selected and the project platform is UWP, why Unity chooses to load standalone XR settings instead.

    If it's operating on the PC, Mac & Linux settings even while UWP is selected and the WMR SDK is the only one in the list, can you file a new bug for us so we can investigate? Thanks!
