DLL NotFoundException on Running VR project.

Unity Engine

Hi,
I’m trying to compile a basic VR unity project just to test the system on my M1 mac. The system I’m using is pretty janky - I am a beginner so forgive me. I’m using an old Vive with an old Beta version of SteamVR. My build settings are set to target Windows x86_64 and I am using the 2021.3.16f1 LTS Unity editor for Silicon.

I keep getting DllNotFoundException errors when attempting to run the project through my VR headset. Any ideas what might be going wrong here?

The exact error is:

DllNotFoundException: UnityOpenXR
UnityEngine.XR.OpenXR.OpenXRLoaderBase.Initialize () (at Library/PackageCache/com.unity.xr.openxr@1.0.3/Runtime/OpenXRLoader.cs:172)

Thanks in advance.

Hey @devushkabeam ,
Does that older version of SteamVR support OpenXR? Is it set as the active OpenXR Runtime? I also wonder if it’s having problems detecting the right architecture between x86 and the M1 (are you running Windows on the Mac or some other program to launch Windows exes?)
