Hi All,

Today i’ve seen, that there is a new Version of Azure CLI.

Let’s check the installed Version

az version

You can initiante the Upgrade to the latest CLI with the following command

az upgrade

The Release notes can be found here Azure CLI release notes

The downloaded MSI starts

Installation is sucessful

But “az version” seems not to be working correctly

az version

So i’ve decided to uninstall the Software

Download the MSI from Install the Azure CLI on Windows

Reinstall the MSI

Now the “az version” is working like expected

az version
