Steps

  1. In Server Manager, click Manage and then select Add Roles
    and Features     to start the Add Roles and Features Wizard.

  2. On the Select installation type screen, select Role-based or
    feature-based installation    .

  3. Select the target server.

  4. On the Select features screen, check the box next to .Net
    Framework 3.5 Features    .

  5. On the Confirm installation selections screen, a warning will
         be displayed asking Do you need to specify an alternate source path? .
         If the target
         computer does not have access to Windows Update, click the Specify an alternate source
    path     link to specify the path to the \sources\sxs folder on the
         installation media and then click OK. After you have specified the
         alternate source, or if the target computer has access to Windows Update,
         click the X next to the warning, and then click Install.

        

         If you are using Server Manager in Windows Server 2012 to add a role
         or feature to a remote server, the remote server’s computer account
         (DOMAIN\ComputerName$) requires access to the alternate source file path
         because the deployment operation runs in the SYSTEM context on the target
         server.
