Windows 8.1 comes with latest version of .NET Framework i.e. 4.5 but, the Windows 8.1 doesn’t come with enabled .NET Framework version 3.0 and 2.0. Some of the desktop utilities still use old 3.0 or 2.0 versions of .NET Framework which can’t work until it is enabled.
Although, whenever the .NET Framework is needed, Windows will ask you to install it from Windows Updates but, it requires internet to be downloaded. Windows 8.1 also asks you to install this feature from Windows Updates but, it fails to download since, the servers are not up yet.
But, the good news is that you can still add .NET Framework 3.0 and 2.0 easily with simple commands without using internet.
Before proceeding to the instructions to enable .NET Framework, you need to fulfill a requirement which has been mentioned below.
- You will need a Windows 8.1 ISO file which you used to install or upgrade Windows 8.1. This ISO file will work as the source of .NET Framework and Windows will install it from that ISO.
Follow the instructions below to enable .NET Framework 3.0 or 2.0 in your Windows 8.1 RTM.
