Doesn't seem to work anymore. If I put the following on a system that doesn't have winget

$releases_url = "https://api.github.com/repos/microsoft/winget-cli/releases/latest"

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$releases = Invoke-RestMethod -uri "$($releases_url)"

$latestRelease = $releases.assets | Where { $_.browser_download_url.EndsWith("msixbundle") } | Select -First 1
	Add-AppxPackage -Path $latestRelease.browser_download_url

I get the following error:

Add-AppxPackage : Cannot process argument transformation on parameter 'Path'. Object reference not set to an instance of an object.

$releases_url = "https://api.github.com/repos/microsoft/winget-cli/releases/latest"

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$releases = Invoke-RestMethod -uri "$($releases_url)"
$latestRelease = $releases.assets | Where { $_.browser_download_url.EndsWith("msixbundle") } | Select -First 1
	
$latestRelease.browser_download_url

Try just the “Add-AppxPackage -Path “ with that url.

How can I install this with Local System account. (I am trying to install winget on the remote Azure VM)
Error while trying to install winget using above script from Azure portal (using RunPowerShellScript for the VM)

Why go such length?

Add-AppxPackage -Path 'https://github.com/microsoft/winget-cli/releases/latest/download/Microsoft.DesktopAppInstaller_8wekyb3d8bbwe.msixbundle'
