Version 2.77 introduced a python error on upgrade, using az upgrade or MSI

[sumsard]

Describe the bug

Specifically for upgrading to version 2.77 using: either

1. az upgrade or
2. azure cli 2.77 MSI file.
   the upgrade will not fail, but running any az command will throw error

I know a fresh install will fix it, but this has been going on for over a month and a new version with a fix has not come out.´
The amount of hours spend around the world on this issue is ridiculous. Many computers will auto update to the latest version.

Related command

az upgrade

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

Perform a clean reinstallation of Azure CLI:

1. Uninstall Azure CLI via Control Panel > Uninstall a program.
2. Delete the directory C:\Program Files\Microsoft SDKs\Azure\CLI2 (for x64) or C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2 (for x86).
3. Reinstall Azure CLI using the MSI installer or another preferred method.

This approach resolves conflicts caused by the MSI installer failing to update certain files related to PyWin32.

Solution 2:

Repair the Azure CLI installation by reinstalling the pywin32 package:

"C:\Program Files\Microsoft SDKs\Azure\CLI2\python.exe" -m pip install pywin32==311 --force-reinstall

This solution repairs the installation by fixing the PyWin32 dependency.

Solution 3:

Downgrade to Azure CLI version 2.76.0:

For example, using winget:

winget uninstall Microsoft.AzureCLI
winget install --exact --id Microsoft.AzureCLI --version 2.76.0

This solution reverts to the previous stable version that does not have the issue.
