Microsoft .NET Framework 4.8 Silent Install (PowerShell)

This article will serve as an informative guide and give you a clear understanding of how to perform silent or interactive installs of Microsoft .NET Framework 4.8 using the Powershell App Deployment Toolkit. The PowerShell App Deployment Toolkit can be used to replace your WiseScript, VBScript and Batch wrapper scripts with one versatile, re-usable and extensible tool. This tool is an absolute must for Microsoft Endpoint Manager Configuration Manager (MEMCM) / (SCCM) Administrators or anyone who is responsible for packaging and deploying software.

How to Install Microsoft .NET Framework 4.8 Using the PowerShell App Deployment Toolkit

Download the Powershell App Deployment Toolkit 3.8.4:
- https://github.com/PSAppDeployToolkit/PSAppDeployToolkit/releases/download/3.8.4/PSAppDeployToolkit_v3.8.4.zip
Download the zip file to a folder created at (C:\Downloads)
Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
Enter the following command to remove the Zone.Identifier:
- Unblock-File -Path C:\Downloads\PSAppDeployToolkit_v3.8.4.zip
Enter the following command to extract the contents of the zip file:
- Expand-Archive -Path C:\Downloads\PSAppDeployToolkit_v3.8.4.zip -DestinationPath C:\Downloads\PADT
Enter the following commands to copy the AppDeployToolkit & Files folders to “C:\Downloads\DotNet48”:
- Copy-Item -Path "C:\Downloads\PADT\Toolkit\AppDeployToolkit" -Destination "C:\Downloads\DotNet48\AppDeployToolkit" -Recurse
- Copy-Item -Path "C:\Downloads\PADT\Toolkit\Files" -Destination "C:\Downloads\DotNet48\Files"

You should now see the AppDeploymentToolkit folder with files & the empty Files folder at “C:\Downloads\DotNet48”

Next we’ll want to download the EXE installer for Microsoft .NET Framework 4.8.

Navigate to: https://go.microsoft.com/fwlink/?linkid=2088631
Download & Copy the ndp48-x86-x64-allos-enu.exe to “C:\Downloads\DotNet48\Files\”
Copy the PowerShell script below to “C:\Downloads\DotNet48” & name it Deploy-DotNet48.ps1

.SYNOPSIS
	This script performs the installation of Microsoft .NET Framework 4.8.
	# LICENSE #
	PowerShell App Deployment Toolkit - Provides a set of functions to perform common application deployment tasks on Windows.
	Copyright (C) 2017 - Sean Lillis, Dan Cunningham, Muhammad Mashwani, Aman Motazedian.

	You should have received a copy of the GNU Lesser General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
.DESCRIPTION
	The script is provided as a template to perform an install or uninstall of an application(s).
	The script either performs an "Install" deployment type or an "Uninstall" deployment type.
	The install deployment type is broken down into 3 main sections/phases: Pre-Install, Install, and Post-Install.
	The script dot-sources the AppDeployToolkitMain.ps1 script which contains the logic and functions required to install or uninstall an application.
.PARAMETER DeploymentType
	The type of deployment to perform. Default is: Install.
.PARAMETER DeployMode
	Specifies whether the installation should be run in Interactive, Silent, or NonInteractive mode. Default is: Interactive. Options: Interactive = Shows dialogs, Silent = No dialogs, NonInteractive = Very silent, i.e. no blocking apps. 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 Destkop Session Hosts/Citrix servers.
.PARAMETER DisableLogging
	Disables logging to file for the script. Default is: $false.
.EXAMPLE
    PowerShell.exe .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "NonInteractive"
.EXAMPLE
    PowerShell.exe .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "Silent"
.EXAMPLE
    PowerShell.exe .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "Interactive"

Ok, all the hard work is done and now you can install Microsoft .NET Framework 4.8 using one single PowerShell script. Logging functionality is built-in automatically and you can view the log files under “C:\Windows\Logs\Software”.

Microsoft .NET Framework 4.8 NonInteractive Install (PowerShell)

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.

Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
Change the directory to “C:\Downloads\DotNet48”
- PS C:\Downloads\DotNet48>
Enter the following command:

Powershell.exe -ExecutionPolicy Bypass .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "NonInteractive"

Microsoft .NET Framework 4.8 Silent Install (PowerShell)

Silent means no dialogs (progress and balloon tip notifications are suppressed).

Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
Change the directory to “C:\Downloads\DotNet48“
- PS C:\Downloads\DotNet48>
Enter the following command:

Powershell.exe -ExecutionPolicy Bypass .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "Silent"

Microsoft .NET Framework 4.8 Interactive Install (PowerShell)

Interactive means the install will show dialogs including progress and balloon tip notifications.

Open Windows PowerShell by Right-Clicking on Windows PowerShell and selecting Run as Administrator
Change the directory to “C:\Downloads\DotNet48”
- PS C:\Downloads\DotNet48>
Enter the following command:

Powershell.exe -ExecutionPolicy Bypass .\Deploy-DotNet48.ps1 -DeploymentType "Install" -DeployMode "Interactive"
