HI,
i recently started my VR-Adventure with a Reverb G2. Everything is fine so far, runs better, than i expected. Only exception is, that the MS Store doesn’t let me download the openXR runtime for WMR. I get the toolkit, but not the runtime. Tried about a dozen tips to fix the store problem to no avail. Is there any possibility to get the runtime installer outside the MS Store?
When I am in MS Store do a search for OpenXR Tools for Windows Mixed Reality
or
The OpenXR Runtime is automatically downloaded when you install the WMR Portal (when you first plug your headset). There is no additional download.
What makes you think that OpenXR is not properly set up?
Exactly. You don’t download the runtime. I think it’s actually part of the MSFS install. OpenXR is a mediator between the game and WMR or any other VR stack (like occulus).
The purpose of it is so that devs can write for OpenXR instead of for WMR, Oculus and whatever other stuff there is.
Kind of like with DirectX.
The tool in the store is a developer / power user tool to override default settings, not the runtime itself.
The WMR Portal itself works, MSFS without SteamVR does not. If i select “setup openXR” from the menu (bottom left) in WMR i get a prompt to download openXR runtime from the store - which fails. If i start the XR-toolkit, it tells me, the openXR runtime for WMR is not installed and prompts me to the same page in the store.
So far i just set the steam version of openXR as active runtime and everything works. But since i read, that the WMR runtime gives better performance, i’d like to try that.
Hey CaptnJackBilbo,
in order to change the runtime do the following:
SteamVR-Runtime depends on where you’ve installed Steam or rather SteamVR itself.
Also notice, that you can download “WindowsMixedReality for Steam VR” via Steam (Link: Windows Mixed Reality for SteamVR on Steam). But that’s not absolutely necessary in order to change the Runtime! 
I hope that I could help you with that.
Best regards and always happy landings

Thanks a lot, on step further. Found the json and .dll on my system and in the registry. Yet, when i try to configure anything in openXR via WMR or Devtools i get a promt, that the runtime app is not installed and a link to the MS Store (right), where my download fails. Thats the app i’m looking for.
Btw. MS-Support couldn’t help and recommended to download the app somewhere outside the store 
It’s not available outside the store, these packages are considered secure and therefore need to go through the store. Your only option is to figure out this store issue with MS.
