If you’re having trouble launching certain apps on your Windows 11 PC, your system may not have the required versions of the .NET Framework installed. It’s easy to install the .NET Framework version 2.0 and 3.5 to troubleshoot your application. Here’s how to do just that.
How to activate the .NET Framework 2.0 and 3.5 on Windows 11
To enable the .NET Framework 2.0 and 3.5 on your Windows 11 PC, you’ll need an active internet connection. This is because the process will download files from the Internet.
When you’re ready, launch the Windows Features dialog on your PC using one of the following three ways:
Option 1: Open the “Start” menu, search for “optional features” and select the item with that exact name.
Option 2: Open the “Run” dialog by pressing Windows + R, type “optional features” and press Enter.
Option 3: Start Control Panel and select Programs > Programs and Features > Turn Windows features on or off.
In the “Windows Features” dialog box, select the “.NET Framework 3.5 (includes .NET 2.0 and 3.0)” check box. Then at the bottom select “OK”.
On the screen that opens, choose “Allow Windows Update to download files for you.” This will begin downloading the files needed to install those versions of the .NET Framework.
When you have installed the versions of the .NET Framework, you will see a success message. Close this window by selecting “Close” at the bottom.
Just to make sure that the newly obtained Framework versions are loaded on your system, restart your PC. Do this by opening the “Start” menu, selecting the “Power” icon, and choosing “Restart.”
When your computer restarts, launch your application and it will work perfectly. Are you ready.

Why enable the .NET Framework 2.0 and 3.5 on Windows 11?
The most common reason you might enable the .NET Framework 2.0 and 3.5 is to fix startup issues with your apps so that you can open them correctly.
The reason is that when a developer builds a Windows program, they use a certain version of the .NET Framework to do it. Then, when the program is ready and you want to run it, you’ll need to have that same version of the .NET Framework installed on your PC. If you don’t have that, your app won’t open.
Microsoft Windows 11 comes with the .NET Framework 4.8, which means that any app designed for this version will work perfectly right out of the box. However, to run applications that are designed for older versions of the .NET Framework, you’ll need to enable those versions on your PC. And that is exactly what we cover in this guide for you.
