Do you have SteamVR installed?
For me:
Problem updated, "Init_PathRegistryNotFound" is gone but the "IPC_connection" is here now.
I saw your comment, then tried Steam + SteamVR + Windows Mixed Reality for SteamVR.
I just find when I use the SteamVR-in-beta plugin in Unity, I get the "IPC_connection" failed. SteamVR throw "301 fatal error", and its window like:
It is weird that Windows Mixed Reality is working smoothly all the time.
Sorry for the trouble shooting request again.
Did you install the "Windows Mixed Reality for SteamVR" drivers off steam? https://store.steampowered.com/app/719950/
I saw your comment, then tried Steam + SteamVR + Windows Mixed Reality for SteamVR.
I installed the "Windows Mixed Reality for SteamVR", what do you mean by "drivers Off steam"? Does that means I should use "Windows Mixed Reality for SteamVR" to install the drivers for VR headset instead of "Windows Mixed Reality"?
Sorry I was not clear. The "Windows Mixed Reality for SteamVR" is software that does translation between SteamVR and Windows Mixed Reality. We commonly refer to them as drivers.
It sounds like you did install the software from that link. Have you tried starting SteamVR since then?
Tried several time.
It is convenient that when I compile my test VR project the SteamVR jumps out automatically but there is always "301 fatal error", and the scene is always black.
I also tried the ways to solve 301 error upon suggestions of steam support: shut down all suspected conflicted software like antivirus and WIFI, from restart SteamVR to computer system, and reinstall the entire Steam. All seemed useless.
Unfortunately I don't see anything obvious. It does look like it sees the driver, but doesn't detect a headset for some reason. You might try posting in the Windows Mixed Reality for SteamVR forums. Microsoft may have better luck helping in this case.
