All permissions are granted at every level Regarding my app dev in Unity, I have already done my due diligence and ensured the following: I already went through the built in 'Hints' app to ensure that voice commands work at least in that built in app. I have successfully built multiple Hololens 2 apps all working great with no issues at all except when I started to try using voice commands. Apparently starting one MSIX registered the scheme, and now your HoloLens can install from the web again.I'm developing using Unity and MRTK. We have done this on two HoloLenses, and it seems to be consistent. If you now go back to your MSIX hosting website, open the app’s website, and hit the install button, the AppInstaller will work as it should. You have now ‘repaired’ your HoloLens 2 AppInstaller. Tap the MSIX until the app installer opens.Open the File Explorer on the HoloLens, navigate to the Downloads folder.Drag an msix - any msix - on your HoloLens using the File Explorer, for instance in the “Downloads” folder.Say WHAT? The appinstaller scheme is unknown? Workaround/solutionĪfter struggling with this for some time I contacted my friend Matteo Pagani, who had one suggestion that did not work, and then one that - weirdly enough - did work! “ Failed to launch ms-appinstaller:?source= because the scheme does not have a registered handler”. My colleague Timmy Kokke suggested to look into the Edge developer tools and then we got to see the most peculiar error: And after flashing we - and our customers - started to hit the following issue: the appinstaller did not start at all after tapping the install button. No sweat here, but at Velicus we distribute apps to our customers using a QR code pointing to a website hosting our MSIX. For instance, because you lived on the edge and it started to misbehave after an Insider’s update.

MSIX install via website does not work anymore after flashing a HoloLensįor some reason you had to flash your HoloLens 2.
