Microsoft .NET Desktop Runtime 9.0 Install and Uninstall (PSADT v4)

Published on: August 19, 2025 | Last Updated on: August 22, 2025 by

This article will serve as an informative guide and give you a clear understanding of how to perform silent or interactive installs and uninstalls of Microsoft .NET Desktop Runtime 9.0 using the PowerShell App Deployment Toolkit v4. The PowerShell App Deployment Toolkit (PSADT) is a collection of PowerShell scripts and functions designed to simplify the deployment of software applications. It helps IT administrators automate tasks such as installing, configuring, and uninstalling applications, and it is commonly used for software packaging and deployment within enterprise environments. PSADT can be used in conjunction with tools like Microsoft Endpoint Configuration Manager (formerly SCCM), Intune, or other deployment systems.

How to Install Microsoft .NET Desktop Runtime 9.0 Using the PowerShell App Deployment Toolkit v4

  • Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
  • Enter the following commands:
Set-ExecutionPolicy Bypass -Scope CurrentUser
Install-Module -Name PSAppDeployToolkit -Scope CurrentUser
Import-Module PSAppDeployToolkit
New-ADTTemplate -Destination 'C:\Temp' -Name 'NETDesktopRuntime9' -Show
  • Navigate to: https://dotnet.microsoft.com/en-us/download/dotnet/9.0
  • Download & Copy the windowsdesktop-runtime-9.0.x-win-x86.exe to “C:\Temp\NETDesktopRuntime9\Files\”
  • Download & Copy the windowsdesktop-runtime-9.0.x-win-x64.exe to “C:\Temp\NETDesktopRuntime9\Files\”
  • Replace the default Invoke-AppDeployToolkit.ps1 template with the script below
<#

.SYNOPSIS
PSAppDeployToolkit - This script performs the installation or uninstallation of an Microsoft .NET Desktop Runtime 9.0.

.DESCRIPTION
- The script is provided as a template to perform an install, uninstall, or repair of an application(s).
- The script either performs an "Install", "Uninstall", or "Repair" deployment type.
- The install deployment type is broken down into 3 main sections/phases: Pre-Install, Install, and Post-Install.

The script imports the PSAppDeployToolkit module which contains the logic and functions required to install or uninstall an application.

.PARAMETER DeploymentType
The type of deployment to perform.

.PARAMETER DeployMode
Specifies whether the installation should be run in Interactive (shows dialogs), Silent (no dialogs), NonInteractive (dialogs without prompts) mode, or Auto (shows dialogs if a user is logged on, device is not in the OOBE, and there's no running apps to close).

Silent mode is automatically set if it is detected that the process is not user interactive, no users are logged on, the device is in Autopilot mode, or there's specified processes to close that are currently running.

.PARAMETER SuppressRebootPassThru
Suppresses the 3010 return code (requires restart) from being passed back to the parent process (e.g. SCCM) if detected from an installation. If 3010 is passed back to SCCM, a reboot prompt will be triggered.

.PARAMETER TerminalServerMode
Changes to "user install mode" and back to "user execute mode" for installing/uninstalling applications for Remote Desktop Session Hosts/Citrix servers.

.PARAMETER DisableLogging
Disables logging to file for the script.

.EXAMPLE
powershell.exe -File Invoke-AppDeployToolkit.ps1

.EXAMPLE
powershell.exe -File Invoke-AppDeployToolkit.ps1 -DeployMode Silent

.EXAMPLE
powershell.exe -File Invoke-AppDeployToolkit.ps1 -DeploymentType Uninstall

.EXAMPLE
Invoke-AppDeployToolkit.exe -DeploymentType Install -DeployMode Silent

.INPUTS
None. You cannot pipe objects to this script.

.OUTPUTS
None. This script does not generate any output.

.NOTES
Toolkit Exit Code Ranges:
- 60000 - 68999: Reserved for built-in exit codes in Invoke-AppDeployToolkit.ps1, and Invoke-AppDeployToolkit.exe
- 69000 - 69999: Recommended for user customized exit codes in Invoke-AppDeployToolkit.ps1
- 70000 - 79999: Recommended for user customized exit codes in PSAppDeployToolkit.Extensions module.

Ok, all the hard work is done and now you can install or uninstall Microsoft .NET Desktop Runtime 9.0 using one single PowerShell script. Simply change the DeploymentType parameter to install or uninstall. Logging functionality is built-in automatically and you can view the log files under “C:\Windows\Logs\Software”.

Microsoft .NET Desktop Runtime 9.0 NonInteractive Install (PSADT v4)

NonInteractive means Very Silent, i.e. no blocking apps. This is automatically set if it is detected that the process is not running in the user session and it is not possible for anyone to provide input using a mouse or keyboard.
