Meta XR Simulator keeps requiring Windows App Runtime 1.5+ even though newer versions are installed

same problem here.   

it works on diff computer.

reinstall XR Sim, windows app runtime x64 x86  

restarted many time, still a problem, not fixed

I had the same issue and was able to narrow it down a bit. In my case, Windows App Runtime 1.5 was already installed, so the problem was not that the OS was missing the runtime itself. The actual issue seemed to be that Meta XR Simulator’s own WinAppRuntime dependency setup was incomplete or broken. After checking the event log, `MetaXRSimulator.exe` was crashing in `Microsoft.WindowsAppRuntime.Bootstrap.dll`, which points to a simulator-side runtime registration problem rather than a normal Windows installation problem.

What fixed it for me was running the bundled runtime installer that comes with the simulator. In my install, it was located at `D:\MetaXR\WindowsAppRuntime\install.bat`. Running that script reinstalls the WinAppRuntime 1.5 packages that the simulator expects. On my machine, some packages were skipped because newer versions were already installed, but one missing dependency package was installed successfully, and after that `MetaXRSimulator.exe` started normally. So if anyone has the same error even though WinAppRuntime 1.5+ is already installed, I would suggest checking the simulator install folder and running its `WindowsAppRuntime\install.bat` script first.

I tried running this install.bat file but it didn't change anything. However, I decided to try manually clicking on the .msix files to see what would happen and one of them wasn't installed. Once that happened, it worked. I believe it was the DDLM one. Hope this helps someone.
