Automation: Download custom TeamViewer with Powershell

C_Is

I needed this and couldn't find a solution online so I sat down and figured this out last night.

In my use case I'm using this in a schedule to monthly get the newest QuickSupport on my Domain-Controller and from there on I distribute it to all domain computers' public desktop.

Note: Make sure to replace "<yourcustomurl>" and the destination path where it should be saved to.

$iebrowser = New-Object -ComObject InternetExplorer.Application
$iebrowser.Navigate('https://get.teamviewer.com/<yourcustomurl>')
Start-Sleep -Seconds 3
$CustomTVQS_URL = $iebrowser.Document.getElementById('MasterBodyContent_btnRetry').href
Start-BitsTransfer -source $CustomTVQS_URL -Destination C:\test\TeamViewerQS.exe

PS: I put a 3 second pause after calling the website URL since it takes a little time to create the ComObject and call the website URL. Powershell is working through the commands too fast and otherwise throws an error that the $CustomTVQS_URL is a null object. You may increase or decrease this if needed.

I noticed some difficulties on automating this on a windows server.

Will update this as soon as I get it fully working and wrote a decent documentation.

Note that you need to:

• configure your Internet Explorer security settings for the 'internet zone':
  • Enable 'Active Scripting'
  • Enable 'File Download'
• configure execution policy for powershell

When using this in task scheduler on a Microsoft Windows Server make sure to set the account to 'System'.

# Download path
$downloadpath = "C:\TeamViewer"
# URL of your customized TeamViewer
$URL = "https://get.teamviewer.com/<yourcustomURL>"

# Function to create the browser object, navigate to the website, isolate the download url and download the TeamViewer QS
function Download_TeamViewerQS () {
    # Internet Explorer application to fool the website into thinking the connection is a client session (this is needed to return the result from javascript function that generates the downloadlink of your custom TeamViewer using the newest version of it)
    $iebrowser = New-Object -ComObject InternetExplorer.Application
    # navigates to the given Website/URL
    $iebrowser.Navigate($URL)
    # Pausing 3 seconds because creating the browser object and navigating to the website takes a little while depending on your system and internet connection
    Start-Sleep -Seconds 3
    # isolates the generated download URL of the custom TeamViewer
    $CustomTVQS_URL = $iebrowser.Document.getElementById('MasterBodyContent_btnRetry').href
    # Downloads the custom TeamViewer QS
    Start-BitsTransfer -source $CustomTVQS_URL -Destination $downloadpath\TeamViewerQS.exe       
}

# Try (creating path and) downloading and catch problem if this is not possible
try {
    Write-Host "Downloading custom TeamViewer QuickSupport..." -BackgroundColor Black -ForegroundColor Yellow
    # Tests if path exists and (creates the path and) downloads TeamViewer QS into it
    if (Test-Path $downloadpath) {
        # Calls the download function
        Download_TeamViewerQS
    } else {
        # Creates the download path if not existent
        New-Item -Path $downloadpath -ItemType Directory | Out-Null
        # Calls the download function
        Download_TeamViewerQS
    }
} catch {
    # Display error if one occurs
    $Error
    # Write information for user
    Write-Host "Download can not be started.`n`nReason: The security settings for `"Internet Zone`" in your Internet Explorer need following configuration:`n- Filedownloads need to be activated`n- Active Scripting needs to be activated" -ForegroundColor Yellow -BackgroundColor Black
    Start-Sleep -Seconds 10
