How to Deploy Software to Multiple Workstations

1. Introduction

Deploying software to multiple workstations in an enterprise can be time and effort consuming. Using automatic deployment tools can optimize this process. We will use MAPILab Mail Merge Toolkit as an example to show the most common (as we see it) modern ways of installing the product on multiple workstations:

  • Mass deployment using MSI file and Group Policy.
  • On-premises package deployment tools such as System Center Configuration Manager (Endpoint Configuration Manager) from Microsoft or from a third-party vendor such as Ivanti Endpoint Manager, ManageEngine Endpoint Central, and others.
  • Cloud-based package deployment tools like Microsoft Intune or third-party alternatives.
  • OS image preparation for virtual desktop environments like Azure Virtual Desktop.

2. Deployment preparation

For historical reasons the MAPILab Mail Merge Toolkit main download is still an .exe file, which contains an .msi package inside. Although the .msi package can be extracted from an .exe file,

Setup.exe /s /x /b"C:\temp\mmt" /v"/qn"
NOTE: Make sure the add-in is not installed in the system before running this command.

for convenience we provide direct links to download the latest version of the MAPILab Mail Merge Toolkit package containing the .msi along with its supporting files:

3. Deployment using Group Policy with MSI and MST files

The good old-fashioned way of installing a software package using Active Directory Group Policies still works.

It is not possible to define registration keys or settings for MSI installation packages within the regular GPO interface. However, if it is necessary to add customization parameters to an MSI package, this can be done using MST transformation files. This type of file allows you to modify the default parameters of an MSI package and customize it to meet specific installation requirements.

We will use an MST file to specify the registration key during deployment.

To create an MST file for an MSI package, you can use the ORCA tool (it is a part of Windows Installer SDK).

Open the MSI package using Orca.

Open MSI using Orca

Once you have Orca opened, choose TransformNew Transform from the menu.

Navigate to the Property table and add row with property of “PRODUCTKEY” and value of your actual product key, e.g., MMP-12345678-12345678:

Product Key

Select TransformGenerate Transform and save the changes as MST file (mmt_mod.mst).

Changes in Orca

Now you can deploy with MSI and MST files.

The first step in deploying the package through GPO is to create a distribution point on the publishing server. This can be done by following these steps:

  • Create a shared network folder (this folder will contain the package files).
  • Set permissions on this folder to allow access to the distribution package.
  • Copy the .msi, .mst along with other files and folders to the shared folder.

Installation files

Then create a new domain Group Policy Object to install the software.

Group policy has settings for targeting computers and settings to target users. In this article, we will target computers for deploying software. This means the software will be installed for anyone that logs onto the computer.

Open the domain Group Policy Management console (gpmc.msc).

In the Group Policy Management console browse to the OU, right click and select “Create a GPO in this domain and Link it here…”.

Group Policy Management

Enter a name for your policy and leave Source Starter GPO as (none).

Edit the GPO and go to Computer ConfigurationPoliciesSoftware SettingsSoftware installation.

Right-click Software Installation and select NewPackage.

Select your package from the previously configured network share.

Select Advanced and click OK.

Deploy Software

Group Policy offers two methods for distributing software packages:

  • Assign – A program can be designated for installation on either a per-user or per-machine basis. When assigned per-user, the program is installed during the user’s login session. Conversely, when assigned per-machine, the program is installed at the machine’s startup, making it available to all users.
  • Publish – A program can be made available to one or more users through publication. In this case, the program is included in the Add or Remove Programs list, allowing users to initiate the installation from there.

Switch to the Modifications tab, click Add and select the MST file from the previously configured network share.


The MST file will now be automatically applied during the MSI installation using the GPO and the application will be installed with the product key.

That completes the GPO configuration. The GPO settings should look like this.

GPO settings

Deployment Information

The program is installed only on reboot, and the GPO settings must be updated on the computer. By default, GPO settings are automatically updated every 90 minutes.

To force this process and ensure that the GPO settings are applied immediately, you can use the “gpupdate /force” command.

When you run the gpupdate command, you will be notified that one or more settings need to be processed before the system starts or a user logs on. This message refers to software that is installed using a GPO and is an expected part of the process. Type Y to restart the computer.

Installing Software

Subsequently, upon rebooting, the software will be installed as intended.

If you want to install software for particular users, just use the user configuration Group Policy Object (GPO) settings rather than those associated with the computer.

4. Microsoft Configuration Manager (ConfigMgr)

4.1 Intruduction

Also known as Microsoft Endpoint Configuration Manager (MECM), System Center Configuration Manager (SCCM) and Systems Management Server (SMS) (Wikipedia).

Microsoft Configuration Manager can deploy applications such as the Mail Merge Toolkit using the Windows Installer package (.msi) or the Setup.exe application. It is also possible to convert an .msi package into a Windows app package (.msix), but this will be covered in a separate article in the future.

Both ways are quite similar, and we will demonstrate how to install the application using each of these options.

Before you start, make sure that the installation files for the Mail Merge Toolkit are in an accessible location on your network (both Setup.exe and .msi with supporting files).

Launch Microsoft Configuration Manager console. Select Software Library, under Application Management select Applications. Right click Applications and select Create Application.

5. Deployment using Microsoft Intune

Microsoft Intune is solely cloud-based technology. It is also called the cloud variant of ConfigMgr, but it is not the equivalent of ConfigMgr. As ConfigMgr is a much more powerful tool than Intune (so far).

In Intune, you can deploy applications to a PC as a Line-of-business app (.msi, .appx, .msix) or as a Windows app (Win32) (.intunewin).

Microsoft Intune Admin Center

Although Mail Merge Toolkit can be deployed by Intune as a LOB app using the .msi package, we recommend using the Windows app (Win32) option using the .intunewin packages available for download at:

The Windows app (Win32) (.intunewin) option provides more control options such as dependencies, delivery optimization, etc.

Log in to the Microsoft Intune admin center, select AppsWindowsAdd.

On the Select app type pane, under the Other, select Windows app (Win32) and click Select.

In the App information step, click Select app package file. Click Browse and select the downloaded .intunewin package. Detailed information about the application appears. Click OK.

Add Package File

Provide additional information about the app, such as the Publisher, Description, Category, and Logo. Click Next.

Add Windows App

At the Program step, the Install and Uninstall commands are filled in automatically.

To automatically apply the product key during deployment, modify the Install command by adding “PRODUCTKEY=MMP-12345678-12345678” (without quotes) to the command line. Click Next.

Make sure that you are using a valid multi-user product key.

Install Command

In the Requirements step, specify Operating system architecture and Minimum operating system version and click Next.

App Requirements

In the Detection rules step, select Manually configure detection rules as the Rules format and click Add.

6. Operation System Image Preparation

This is the simplest part of an article. In virtualized desktop environments such as Azure Virtual Desktop, custom software can be included in a so-called “golden image” for session hosts.

There are a number of articles on how to prepare a golden image, e.g. :

They all include the step of installing custom software.

In the case of Mail Marge Toolkit, you need to install the software either using a regular installer and enter the product key or run the installation from the command line with the product key.

"Setup for Outlook 64-bit.exe" /s /v"ALLUSERS=1 PRODUCTKEY=MMP-12345678-12345678 /qn"

Once the installation is complete, you can proceed with taking the final snapshot and running Sysprep.
