Error – The following feature couldn’t be installed – .NET Framework 3.5


 
I got error this message on a pop window while running a new application after installing it on my Windows Server 2012 Azure VM.


 

This feature can be installed from the “Windows Server Manager”, you will see its icon on the task bar besides the Start button, as shown below. Or you can directly type “servermanager” on CMD or Run prompt.

Click on the “Add Roles and Features”


 

A new window will open up “Add Roles and Features Wizard”, click Next.
On “Installation Type”, click Next again.
On “Server Selection”, select the current/default server and click Next.
On “Server Roles” click Next.
Now on Features select the “.NET Framework 3.5 Features” option, an click Next.
On Confirmation page you will see “Specify an alternate source path” link, click on that link, and a new window opens up, as shown below:


 

Here on the highlighted text box you need to specify the “side-by-side (SxS) folder” path of the OS installation media. So, if you have an ISO file you can mount it or if you have a dump of the setup, provide the path form the respective location. Finally click on Install button.
 

If you are on an Azure Windows VM, you will not have access to the ISO or installation media. In this case you can simply run a Windows Update from Control Panel–> System and Security –> Windows Update.
