TeamViewer Host Deployment Scripts

These scripts are designed to install, uninstall, and check the presence of TeamViewer Host on Windows machines. They can read parameters from the command line, a configuration file (config.json), or use default values. If any required parameter is missing and cannot be resolved, the scripts will fail with an appropriate error message.

Configuration

The scripts use a configuration file (config.json) to store default values for the TeamViewer Host settings. Here is an example of the configuration file:

{
    "ConfigID": "ABC123",
    "AssignmentID": "AAAAABBBBBCCCCDDDDEEEE11112222333344445555=",
    "Logging": false,
    "NoShortcut": true,
    "DeviceAlias": "%COMPUTERNAME%",
    "InstallerPath": "./TeamViewer_Host.msi",
    "InstallSecurityKeyRedirection": false,
    "SettingsFile": "./TeamViewer_Settings.tvopt"
}

Parameters

• ConfigID: The custom configuration ID for TeamViewer installation.
• AssignmentID: The assignment ID for TeamViewer.
• Logging: Enables transcript logging if set to true.
• NoShortcut: If set to true, disables the creation of desktop shortcuts during installation.
• DeviceAlias: Specifies the device alias. If not provided, defaults to %COMPUTERNAME%.
• InstallerPath: The path to the TeamViewer_Host.msi installer. Defaults to ./TeamViewer_Host.msi.
• InstallSecurityKeyRedirection: Installs security key redirection during if set to true. Default is false.
• SettingsFile: Specifies the path to a settings file that contains configuration settings for TeamViewer. Defaults to nothing unless specified.

Obtaining TeamViewer_Host.msi

You must download the TeamViewer_Host.msi installer from the TeamViewer Management Console. Once downloaded, place the installer in the same directory as the script or specify the path using the InstallerPath parameter.

You can also use these direct links:

• TeamViewer MSI (64 bit)
• TeamViewer MSI (32 bit)

The links are to TeamViewer's official download server. The downloads include the MSI-package for both TeamViewer Host and TeamVIewer Full.

Path Considerations

config.json

The scripts assume relative paths for the config.json. It uses a relative path to config.json in the same directory as the script. This ensures that the scripts can locate the necessary files correctly when deployed in different environments, such as through Intune.

TeamViewer_Host.msi

The InstallerPath parameter supports both relative and absolute paths. By default, it uses a relative path to TeamViewer_Host.msi in the same directory as the script. You can specify an absolute path if the installer is located elsewhere on the system.

Install Script

Description

The install script adds TeamViewer using the specified parameters.

Usage

To run the install script, use the following command:

.\install.ps1 -ConfigID "<ConfigID>" -AssignmentID "<AssignmentID>" [-Logging] [-NoShortcut] [-DeviceAlias "<DeviceAlias>"] [-InstallerPath "<InstallerPath>"] [-InstallSecurityKeyRedirection] [-SettingsFile "<SettingsPath>"]

Parameters

• ConfigID: The configuration ID for TeamViewer installation.
• AssignmentID: The assignment ID for TeamViewer.
• [Optional] Logging: Enables transcript logging if set.
• [Optional] NoShortcut: Disables the creation of desktop shortcuts if set.
• [Optional] DeviceAlias: Specifies the device alias. Defaults to %COMPUTERNAME%.
• [Optional] InstallerPath: Specifies the path to the TeamViewer_Host.msi installer. Defaults to ./TeamViewer_Host.msi.
• [Optional] InstallSecurityKeyRedirection: If set, adds INSTALLSECURITYKEYREDIRECTION=1 to the MSI install arguments. Defaults to false.
• [Optional] SettingsFile: Specifies the path to a settings file. Adds SETTINGSFILE="path" to the MSI arguments. Defaults to nothing.

Fallback to Configuration File

If a parameter is not provided via the command line, the script will attempt to read it from the config.json file. If the parameter is still not available, the script will fail and provide an error message.

Example

To specify values directly via the command:

.\install.ps1 -ConfigID "ABC123" -AssignmentID "AAAAABBBBBCCCCDDDDEEEE11112222333344445555=" -Logging -NoShortcut -DeviceAlias "ACCOUNTING_%COMPUTERNAME%" -InstallerPath "./TeamViewer_Host.msi" -InstallSecurityKeyRedirection -SettingsFile "./TeamViewer_Settings.tvopt"

To use the default values from the configuration file:

.\install.ps1 -Logging

Script Workflow

1. Start the installation of TeamViewer using msiexec.exe.
2. Wait for 30 seconds for the installation to complete.
3. Verify the existence of TeamViewer.exe.
4. Run the assignment command with the provided AssignmentID and DeviceAlias.

Uninstall Script

Description

The uninstall script removes TeamViewer Host using the specified parameters.

Usage

To run the uninstall script, use the following command:

.\uninstall.ps1 [-Logging]

Parameters

• [Optional] Logging: Enables transcript logging if set.

Fallback to Configuration File

If a parameter is not provided via the command line, the script will attempt to read it from the config.json file. If the parameter is still not available, the script will fail and provide an error message.

Example

To specify values directly via the command:

.\uninstall.ps1 -Logging

To use the default values from the configuration file:

.\uninstall.ps1

Script Workflow

1. Retrieve the product GUID for TeamViewer.
2. Uninstall TeamViewer using msiexec.exe.

Check Script

Description

The check TeamViewer Host script verifies if TeamViewer Host is installed and outputs "Detected" or "NotDetected". It uses exit codes compatible with Intune: 0 for success (detected) and 1 for failure (not detected).

Usage

To run the check script, use the following command:

.\check.ps1 [-Logging]

Usage without config.json or Command Arguments

If you are running this as a check script in environments such as Intune, it is best to populate the variables directly in the code. Intune does not allow passing CLI arguments or using config.json for check scripts, so the only way is to set the variables within the script itself.

The script includes a section designed for this purpose:

# Manually fill these variables if using environments like Intune 
# (Intune does not support CLI arguments or configuration files for check scripts)
#
# $ManualLogging = $false  # Set to $true to enable logging

To use this feature, simply uncomment these lines and populate the variables with your desired values. The script will prioritize these manual settings over CLI arguments and config.json, ensuring that the specified data is used during execution. This approach allows seamless integration with Intune and similar deployment tools.

Parameters

• [Optional] Logging: Enables transcript logging if set.

Fallback to Configuration File

If a parameter is not provided via the command line, the script will attempt to read it from the config.json file. If the parameter is still not available, the script will fail and provide an error message.

Example

To specify values directly via the command:

.\check.ps1 -Logging

To use the default values from the configuration file:

.\check.ps1

Script Workflow

1. Check if the Logging parameter is provided.
2. Start transcript logging if enabled.
3. Check if TeamViewer.exe exists in the expected locations.
4. Output "Detected" if TeamViewer is found, otherwise output "NotDetected".

Logging

Description

All scripts support transcript logging to capture detailed information about the script execution. Logging can be enabled via the -Logging parameter or the configuration file.

How It Works

When logging is enabled, the scripts will start a PowerShell transcript at the beginning of the execution and stop it at the end. This transcript will include all commands executed and their output, providing a detailed log of the script's actions.

Enabling Logging

Logging can be enabled by setting the -Logging parameter when running the script, or by setting the Logging property to true in the config.json file.

Log File Location

The log files are stored in the temporary directory of the user running the script. The log file names follow the pattern:

• For the install script: installation_log_TeamViewerHost_${ConfigID}.txt
• For the uninstall script: uninstallation_log_TeamViewer.txt
• For the check script: check_TeamViewerHost_log.txt

Example log file paths:

• C:\Users\<Username>\AppData\Local\Temp\installation_log_TeamViewerHost_ABC123.txt
• C:\Users\<Username>\AppData\Local\Temp\uninstallation_log_TeamViewer.txt
• C:\Users\<Username>\AppData\Local\Temp\check_TeamViewerHost_log.txt

System Account Exception: When scripts are run as the System account, such as during automated deployments or via certain administrative tools, the log files will be stored in the C:\Windows\Temp directory instead of the user's local temporary directory.

Example

To enable logging via the command line:

.\install.ps1 -ConfigID "ABC123" -AssignmentID "AAAAABBBBBCCCCDDDDEEEE11112222333344445555=" 

Or by setting the Logging property in the configuration file:

{
    "ConfigID": "ABC123",
    "AssignmentID": "AAAAABBBBBCCCCDDDDEEEE11112222333344445555=",
    "Logging": true,
    "NoShortcut": true,
    "DeviceAlias": "%COMPUTERNAME%"
    "InstallSecurityKeyRedirection": false,
    "SettingsFile": "./TeamViewer_Settings.tvopt"
}

Error Handling

All scripts include error handling to provide clear messages when parameters are missing or actions fail. If any required parameter is missing and cannot be resolved, the scripts will fail with an appropriate error message.

Notes

• Ensure that you have the necessary permissions to install and uninstall TeamViewer Host on the machine where these scripts are executed.
• The scripts assume that the necessary files are available at the specified paths.

Troubleshooting

If you encounter any issues, ensure that all parameters are correctly specified and that the necessary files are available at the provided paths. Check the error messages provided by the scripts for further details on what might have gone wrong.
