I need to update Azure CLI on a machine I don't administer but where I can run scripts remotely and thus I basically have CLI access. When using the recommended PowerShell script to install Azure CLI, modified so that is does not hang inside Invoke-WebRequest and so that it logs the installation details, I see the installation fails with log message "Failed to connect to server. Error: 0x80070005".
I looked up the error code 0x80070005 means "Access Denied by DCOM". I also read that the "server" is actually the Windows Installer service commanded by the msiexec client.
Is it possible to upgrade the Azure CLI without assistance of the machine's administrator? How to investigate further in this direction?
My script so far:
Invoke-WebRequest -Uri https://aka.ms/installazurecliwindows -OutFile AzureCLI.msi -UseBasicParsing Start-Process msiexec.exe -Wait -ArgumentList '/I AzureCLI.msi /quiet /L*v! AzureCLI.log' Get-Content AzureCLI.log rm AzureCLI.msi, AzureCLI.log
The log is:

In the past, I was able to install Azure CLI on several such machines from scratch, using the above mentioned recommended PowerShell oneliner. The machine is an Azure DevOps Server agent and I can edit and run Azure Pipelines that use it. I know I should best ask the administrators, but they are in a separate department of the enterprise and they are notoriously inaccessible, unreliable and they let everyone jump through stupid meaningless hoops. Our Scrum team found it is usually most efficient when we ourselves take care of everything we technically can and only ask them for things only they can do.
Thought about using
az upgrade, but it calls
powershell.exe -NoProfile "Start-Process msiexec.exe -Wait -ArgumentList '/i https://aka.ms/installazurecliwindows'" under the hood, which is not an unattended installation (
/quiet is missing). It saves the MSI download when the current version is already installed and handles also other package managers on other OSes, but I don't need any of this right now.
Also thought about using a tool installer task but I do not know about any for Azure CLI, certainly not in our DevOps Server.
