If you need to run older programs
Repair .NET Framework 3.5 (including .NET 2.0 and 3.0) Windows 8/10
Windows 8/10 comes with .NET Framework 4.5 installed by default. Since .NET 4.5 is an in-place upgrade from 4.0, you can automatically run any applications that target .NET Framework 4.5 or 4.0. That's fine, but what if you need to run programs that require older versions of .NET Framework? What is the lowest version you can run?
In Windows 8/10, .NET 3.5, 3.0 and 2.5 are shipped with the operating system, you just need to enable it. This is very convenient because you don’t need to download .NET 3.5 from the Microsoft website. In this post, I will show you how to enable the older versions of the .NET Framework in Windows 8/10.
In Windows 8, first go to the Start screen and start typing “Turn Windows on…” and click on Settings in the Charms bar. You should see an option called Turn Windows features on or off.
