'Installer failed with exit code: 0x80070002 : The system cannot find the file specified.' when updating AppInstaller package

[shocko (shockogit)]

Our IT sec team block the usage of MS Store UI via group policy. Many of our machines do not have the AppInstaller package nor winget so I have been looking at installing manually to test and therafter looking to distibute via MECM. I'm a local administrator so I install the MSIXBundle package as follows offline:

PS > Add-AppxPackage -path 'Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.msixbundle'

It installs fine and I cna now use Winget. However, this verison of the AppInstaller is somewhat old

PS > (Get-AppxPackage -Name Microsoft.DesktopAppInstaller).Version 1.22.11132.0

So naturally I run winget update Microsoft.AppInstaller but I get the following:

`Found App Installer [Microsoft.AppInstaller] Version 1.23.1911.0
This application is licensed to you by its owner.
Microsoft is not responsible for, nor does it grant any licenses to, third-party packages.
This package requires the following dependencies:

• Packages
  Microsoft.UI.Xaml.2.8 [>= 8.2310.30001.0]
  Successfully verified installer hash
  Starting package install...
  Installer failed with exit code: 0x80070002 : The system cannot find the file specified.`

Why is this?

The App Installer has UI components which is why there is a dependency on UI.XAML.

You may have better results using Repair-WinGetPackageManager -Latest -Force in the Microsoft.WinGet.Client PowerShell module.

Note: Repair works in Windows PowerShell but several of the other cmdlets do not work in Windows PowerShell.
