Attempting to register a remote machine on Team Services

I am attempting to register a remote machine on team services with Powershell. When I enter the script on the remote machine and attempt to run it, I get the error below: Cannot add type. The assembly 'System.IO.Compression.FileSystem' could not be found. I have copied the registration script from the Deployment Groups section on team services online.

The server that I am using is windows server 2008 R2. The script is below:

$ErrorActionPreference="Stop";If(-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] “Administrator”)){ throw "Run command in Administrator PowerShell Prompt"};If(-NOT (Test-Path $env:SystemDrive\'vstsagent')){mkdir $env:SystemDrive\'vstsagent'}; cd $env:SystemDrive\'vstsagent'; for($i=1; $i -lt 100; $i++){$destFolder="A"+$i.ToString();if(-NOT (Test-Path ($destFolder))){mkdir $destFolder;cd $destFolder;break;}}; $agentZip="$PWD\agent.zip";(New-Object Net.WebClient).DownloadFile('https://github.com/Microsoft/vsts-agent/releases/download/v2.116.1/vsts-agent-win7-x64-2.116.1.zip', $agentZip);Add-Type -AssemblyName System.IO.Compression.FileSystem;[System.IO.Compression.ZipFile]::ExtractToDirectory($agentZip, "$PWD");.\config.cmd --deploymentgroup --agent $env:COMPUTERNAME --runasservice --work '_work' --url 'https://aaosprojects.visualstudio.com/' --projectname 'xxxxxxxProjects' --deploymentgroupname "xxxxxxxxxDeploymentGroup" ; Remove-Item $agentZip;
