<h2>Installation of Chocolatey Client</h2>
<p>Chocolatey Client is part of public Windows images from November 2024. On Servers deployed from older images the Chocolatey client must be installed manually. MS Windows Server 2019 and before requires .net 4.8 additionally and requires an additional reboot.</p>
<p>Installation can be done with these commands:</p>
<pre><code># define chocolatey server of your region
$ChocoServer = 'chocolatey.eu-de.otc-service.com'
# $ChocoServer = 'chocolatey.eu-nl.otc-service.com'
# test network connection to Chocolatey server
if ( ! (Test-NetConnection $ChocoServer -port 80).TcpTestSucceeded ) {
Write-Error "Error: no connetation to ChocoServer: $ChocoServer"
pause
Exit 1
}
# check for pending reboots
if (Test-Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\RebootPending") {
Write-Error "A reboot is required. `n If you encounter errors, reboot the system and attempt the operation again"
pause
Exit 1
}
# install .net 4.8 - if not allready done
if ((Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" -ErrorAction SilentlyContinue).Release -lt 528040) {
$DownloadFile = 'ndp48-x86-x64-allos-enu.exe'
$url = "http://$ChocoServer/$DownloadFile"
$outpath = "$env:temp\$DownloadFile"
Invoke-WebRequest -Uri $url -OutFile $outpath
Start-Process -Filepath $outpath -ArgumentList "/q /norestart" -wait
start-sleep 10
Remove-Item $outpath -ErrorAction SilentlyContinue
}
# check for pending reboots
if (Test-Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\RebootPending") {
Write-Error "A reboot is required. `n If you encounter errors, reboot the system and attempt the operation again"
pause
Exit 1
}
# download and install the client - if not already done
Set-ExecutionPolicy Bypass -Scope Process -Force
