Hi,

Today I got below error screen when I try to install .Net 3.5 Framework SP1 on my WIN 2008 R2 server .

Reason :-

• Windows 2008 R2 natively ships with the .NET 3.5 SP1 framework.
• So, it wont allow us to run the .Net 3.5 framework setup file.

Workaround :-

• As Windows 2008 R2 ships with the .NET 3.5 SP1, We just need to enable the feature from “Server Manager“.

Steps to enable feature on Server Manager :-

• Click on “Start” button and type keyword “Server”
• Double click on “Server Manager” link

• On the “Server Manager” window, Choose “Features -> Add Features”

• Check the “Dotnet Frameowrk 3.5.1 Features” check box

• Restart the server

Hope it helps 🙂
