Setup deployment group agent with powershell failed

Question

I try to run the script provided in “deployment group” section on my Win7 VM (what I do is just “copy\paste\run”).

$ErrorActionPreference="Stop";
If(-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent() ).IsInRole( [Security.Principal.WindowsBuiltInRole] “Administrator”)){ throw "Run command in an administrator PowerShell prompt"};
If($PSVersionTable.PSVersion -lt (New-Object System.Version("3.0"))){ throw "The minimum version of Windows PowerShell that is required by the script (3.0) does not match the currently running version of Windows PowerShell." };
If(-NOT (Test-Path $env:SystemDrive\'azagent')){mkdir $env:SystemDrive\'azagent'};
cd $env:SystemDrive\'azagent'; 
for($i=1; $i -lt 100; $i++){$destFolder="A"+$i.ToString();
if(-NOT (Test-Path ($destFolder))){mkdir $destFolder;cd $destFolder;break;}}; 
$agentZip="$PWD\agent.zip";
$DefaultProxy=[System.Net.WebRequest]::DefaultWebProxy;$securityProtocol=@();$securityProtocol+=[Net.ServicePointManager]::SecurityProtocol;
$securityProtocol+=[Net.SecurityProtocolType]::Tls12;[Net.ServicePointManager]::SecurityProtocol=$securityProtocol;
$WebClient=New-Object Net.WebClient; 
$Uri='https://vstsagentpackage.azureedge.net/agent/2.204.0/vsts-agent-win-x64-2.204.0.zip';
if($DefaultProxy -and (-not $DefaultProxy.IsBypassed($Uri))){$WebClient.Proxy= New-Object Net.WebProxy($DefaultProxy.GetProxy($Uri).OriginalString, $True);};
 $WebClient.DownloadFile($Uri, $agentZip);
Add-Type -AssemblyName System.IO.Compression.FileSystem;
[System.IO.Compression.ZipFile]::ExtractToDirectory( $agentZip, "$PWD");
.\config.cmd --deploymentgroup --deploymentgroupname "MY_GROUP_NAME" --agent $env:COMPUTERNAME --runasservice --work '_work' --url 'https://dev.azure.com/MY_ORG_NAME/' --projectname 'MY_PROJ_NAME';
 Remove-Item $agentZip;

And error occurs:

Here is the info of powershell version:

Any suggestion is appreciated.

Answer 1

As mentioned in the question comments, the issue stems around faulty quotation marks in the provided registration script.

It seems to only affect more modern Windows/PowerShell versions, so it hasn't been addressed by Microsoft with any priority yet. For now, the workaround is to find and replace.

If you paste the script into a text editor, search for “Administrator” and replace with "Administrator".

If you paste the script into (a modern) PowerShell prompt directly, the faulty characters will be stripped and you will need to manually add them:
