When managing a corporate network, administrators often have to install and configure software on multiple workstations at the same time so that one does not have to spend time on manual configuration of each computer.

One of the ways to do this task on Windows is to use group policies for installing the configured application on all computers within the domain. However, this solution is possible only if the MSI package of the application is available.

In this article we will show how to install TrueConf client application with predefined parameters on all machines within the domain and locally on one of these machines.

The installation with specified parameters should be performed by the user with administrator rights. This detail should be taken into account if you do not want to strictly follow the instructions and install the software manually or with a third-party script (e.g., PowerShell).

Why MSI packages are needed

An .msi file (abbreviated from Microsoft Installer) is an installer for Windows. Under the hood, it is a container with instructions and data needed for installing the specific application.

For a regular Windows user, it is more common to install software with executive (.exe) files. MSI installation is more widespread in business settings because this approach offers the following advantages:

  • Ability to deploy an MSI package on multiple computers within the corporate network with group policies.
  • Ability to configure the installation process with the help of parameters (in the context of MSI, these parameters are called keys) and pass these parameters to the application (this feature has to be supported by the developers).

Where can I find MSI installer of TrueConf client application?

You can download the MSI installer of TrueConf client application from the official website. To do it, follow this link and click the Download for free button. In the pop-up window, click on the button for downloading the MSI application installer.

List of installation keys

When TrueConf client application is deployed from an MSI package, all specified parameters will be included in the settings.json file stored in the folder where the application is installed. One can edit it to add/change/delete certain settings. However, you should keep in mind that the name of an MSI key that determines one of the application settings, may not match its identifier in the JSON file. The list of all MSI keys and corresponding JSON identifiers is included in the PDF file which can be downloaded by clicking on the button below:

Getting ready MST file to specify settings when installing with group policies

The keys for the MSI package installed with the help of group policies have to be specified in the .mst file. One can create such a file with the help of the Orca tool which is part of the Microsoft Windows Installer SDK.

The steps that will be described below can be performed on any machine. It does not have to be located in the target domain:

  1. Download the Windows SDK installer from the official Microsoft website and run it.
  2. Within the context of this task, one only needs to check the box MSI Tools when selecting the components to be installed.

  3. Next, go to the directory where Windows SDK tools were installed (by default, it is C:\Program Files (x86)\Windows Kits). From this folder, follow this path \bin\sdk_version\x86 (sdk_version will be replaced with the version of your Windows SDK). Here, you can find the MSI installer of the Orca tool. As a rule, it is the file named Orca-x86_en-us.msi. Install and run this tool.
  4. Open the MSI package of TrueConf client application by going to File → Open in the menu:

  7. Specify the values of the required keys in the Value column.

    The values of some parameters can be used only in combination with other parameters. For example, if the value of the corporateServer parameter is set to true (this parameter is responsible for automatic connection to the server when the application is started), you have to specify the userDefinedServerHost parameter with the required address. All the parameters that have to be used in pairs are marked in the PDF file mentioned above.

Installing MSI package with group policies

To deploy TrueConf client application on all the machines included in the domain, one has to perform the following actions on the controller of this domain:

  1. Place the MSI installer of the client application and the MST file with predefined keys on the domain controller at the following path:

    \\your.domain\SYSVOL\your.domain.controller\scripts

    The SYSVOL directory must be available for detection by client machines in the domain. Otherwise, installation will be impossible.
