Microsoft's .NET Framework is a programming platform that includes programming libraries that can be installed or are already included in Windows operating systems. Depending on your needs, your computer must install the .NET Framework program. However, computers running Windows 8 and above, especially Windows 10, have problems installing .NET Framework 3.5.
In this article, WebTech360 will guide you step by step to fix the error of not installing .NET Framework 3.5 on your computer.
Why is .NET Framework 3.5 so important?
Although the latest version, .NET Framework 4.5.2, comes pre-installed in Windows, users will always need an earlier version of the framework to run specific applications that require 3.5 or earlier. Version 3.5 can also be installed alongside version 4 or later. This is why it is so important to install .NET Framework 3.5 on your Windows system so that older applications can function properly.
