Notepad++ Install and Uninstall (PSADT v4)

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 Notepad++ 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 Notepad++ 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 'Notepad++' -Show

Navigate to: https://notepad-plus-plus.org/downloads/
Download & Copy the npp.x.x.Installer.exe to “C:\Temp\Notepad++\Files\”
Download & Copy the npp.x.x.Installer.x64.exe to “C:\Temp\Notepad++\Files\”
Optional: Copy the config.model.xml to “C:\Temp\Notepad++\Files\”
- See the Notepad++ 8.7 Silent Install (How-To Guide) for instructions on how to generate the config.model.xml
Replace the default Invoke-AppDeployToolkit.ps1 template with the script below

<#

.SYNOPSIS
PSAppDeployToolkit - This script performs the installation or uninstallation of Notepad++.

.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), or NonInteractive (dialogs without prompts) mode.

NonInteractive mode is automatically set if it is detected that the process is not user interactive.

.PARAMETER AllowRebootPassThru
Allows the 3010 return code (requires restart) to be 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 -DeployMode Silent

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

.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.
