Inexplicable 0x80070020/0x80073CF6 when installing Msix

[AliveDevil]

Brief description of your issue

When installing an MSIX directly AppInstaller inexplicably returns 0x80073cf6/0x80070020 insufficient memory, and fails the installation.

Steps to reproduce

Not sure, but what's been done:

• Install App by AppInstaller
• Test app
• Downgrade App for testing an integrated updater, by using a specific version Msix package
  • Whether the App was previously installed doesn't seem to make a difference, when uninstalling the newer, then installing the previous version, the error is the same.

We've seen this happen occasionally, without having identified the root cause - I couldn't reproduce it on my machine.

Expected behavior

Detailed error description, not just "Insufficient Memory" so in-house support teams can act upon this, instead of deferring and hoping this gets resolved some day.

It looks like you are reporting an issue with App Installer as opposed to WinGet.

[AliveDevil]

Sorry for reporting it here, but I've not found other constructive ways to report AppInstaller feedback. I'd be happy if you forward this to the appropriate team to look into this, but in case this is out of reach, please close this, and I'll check for other channels.

I do work with several folks on the MSIX team. I'll see if I can route this to someone to take a peek and offer some guidance.

My first pass yielded:

80073cf6 = ERROR_INSTALL_REGISTRATION_FAILURE 0x80070020 = ERROR_SHARING_VIOLATION

0x14 / 0x80070014 = ERROR_OUTOFMEMORY (Not sure how out of memory came from the above errors).
