I have 2 version of OpenXR installed on my rig. OpenXR for Windows Mixed Reality and OpenXR Development for WMR. Can I both uninstall or is the 1st one the WMR Portal? I also have Windows Mixed Reality for SteamVR installed if I check my app library under W10. That’s why I’m asking.
I uninstalled first both, but when opening WMR Portal I get a warning that openXR is not configured. Can I ignore this? I kept the installation of OpenXR for WMR, installed OpenXR Developer only for the moment and until I get your feedback on this. I use my Reverb G2 not only for FS2020, have several racesims installed via Steam 
Many thanks for clarification and your kind support.
