Install or Upgrade Duo Authentication for Windows Logon

January 5, 2026

In this post, I will show you how to use my Duo Authentication for Windows Logon PowerShell scripts to check whether Duo Win Logon is installed, install Duo Win Logon, or upgrade Duo Win Logon.

Previously, I wrote the blog post Upgrading Duo Authentication for Windows Logon. That blog post covered how to upgrade Duo Win Logon using the MSI. However, later on, Duo changed Duo Win Logon enough that the application now requires Microsoft Visual C++ 2022 Redistributable, which is not bundled with the MSI installer but is bundled with the EXE installer.

Another limitation of the MSI deployment is that you need to create a transform file to silently install Duo Win Logon. With the EXE installer version of Duo Win Logon, you can specify everything with silent install arguments.

The PowerShell Scripts

Duo-Win-Logon-Checker.ps1

The first PowerShell script checks if Duo Win Logon is installed and reports its version. It is a refactored version of the duo-checker function from the Duo Win Logon MSI upgrade script.

The script uses the Prog-Finder function from the Install Matrix project.

It also tells you if the version of Duo Win Logon is old. For the old version detection to work correctly, you will need to edit the NewVersion variable. You can check for Duo Win Logon releases by reviewing the Duo Win Logon release notes.

Duo-Win-Logon-Install.ps1

This script uses various functions from the Install Matrix project to install Duo Win Logon.

For this script to work, you will need to edit the InstallArgs variable.

Install Matrix

January 4, 2026

At EUC World Amplify 2025, I gave a presentation titled “Transforming Chaos into Control: Mastering Windows App Deployments with Intune“. The presentation covered the ways I’ve been deploying applications with Intune that aren’t just repackaging the same Win32 application each time there’s an update. Instead, I package a PowerShell script as a Win32 application.

If you are interested in the presentation, I created a landing page on GitHub that includes the PowerPoint file. You can find that on my GitHub here.

Presenting the Install Matrix at EUC World Amplify 2025.

During the presentation, I introduced a GitHub project called the Install Matrix that I created in collaboration with a coworker. The goal of the Install Matrix is to modularize each part of a PowerShell install script into functions that can be reused in new PowerShell scripts to install applications. The Install Matrix helps reduce duplicate work, making it quick and easy to package applications and reducing overhead when updating them.

In this post, I’ll show you how you can use the Install Matrix in your own PowerShell scripts.

Putting it Together

When creating a PowerShell application install script with the Install Matrix, the first step is to set the script’s defaults. Typically, this will include the temp folder, the silent install arguments, and a download URL.

Usually, I define these as CmdletBinding, allowing for simple parameter changes if needed.

Example

  [CmdletBinding()]
  param (
      [string]$TempDir = "C:\Temp",
      [string]$InstallArgs = '/S',
      [string]$DownloadUrl = "https://download.website.com/program.exe"
  )Code language: PowerShell (powershell)

For the download URL, if the application vendor doesn’t have an always-current URL, I recommend setting up your own URL shortener so you can update the URL for new versions without changing the script or repackaging.
