Not a developer, just need to install OpenXR in order to experience VR for Architecture using Twinmotion.
My employer blocks the Microsoft Store, but I have Local Admin in my PC. Is there a download and instructions for simple mortals that were send to you by the Meta Quest support team?
Exception: Xrresult failure [XR_ERROR_INSTANCE_LOST] Origin: xrCreateInstance
Thank you!
OpenXR itself is not a software you can install, it is a developer API for programming VR applications. Since you are not a developer it seems unreasonable for Meta support to direct you to a developer resource.
If you have successfully connected your VR headset to your PC and installed the software from your headset vendor, you should already have everything needed to run applications that use OpenXR.
I suggest contacting the support for the application you are trying to run, or contacting Meta support again.
Totally agree. I need the OpenXR Runtime app, not the sdk.
Thank you for your time 
Exactly, and you need the runtime is specific to your headset vendor. Microsoft’s runtime only works for Windows Mixed Reality headsets.
