How to install .NET Framework 3.5 on Windows Server 2012 and Windows Server 2012 R2

Symptom: When trying to add the .NET Framework 3.5 feature through the Add Roles and Features Wizard in Server 2012 (R2), you receive the following error:

Do you need to specify an alternate source path?  One or more installation selections are missing source files on the destination server.  The server will try to get missing source files from Windows Update, or from a location that is specified by Group Policy.  You can also click the “Specify an alternate source path” link on this page to provide a valid location for the source files.

NET Framework 3-5 - Do you need to specify an alternate source path

Solution: Complete the steps below to manually install .NET Framework 3.5 from the Server 2012 (R2) installation media.  You can complete this task via command line or via the wizard.

  1. Option 1: Command Line
    1. Insert the Windows Sever 2012 installation media
      Server 2012 - Installation Media
    2. Open up an elevated command prompt
      Elevated Command Prompt
    3. Execute the following command
      1. dism /Online /Enable-Feature /FeatureName:NetFX3 /All /Source:D:\Sources\SxS\ /LimitAccess
        dism netfx3 from disk

        1. Here is a breakdown of the following command:
          /Online                 – Targets the running operating system.
          /Enable-Feature – Enables a specific feature in the image.
          /All                          – Enables all parent features of the specified feature.
          /LimitAccess        – Prevents DISM from contacting WU/WSUS.
  2. Option 2: GUI
    1. Insert the Windows Sever 2012 installation media
      Server 2012 - Installation Media
    2. On the Add Roles and Features wizard, click on Specify an alternate source path
      NET Framework 3-5 - Specify an alternate source path
    3. Enter D:\Sources\SxS\ to point to the Server 2012
      NET Framework 3-5 - Specify an alternate source path - Dialog

Once done installing through the GUI or command prompt, if you navigate back to the Add Roles and Features Wizard, you should see the feature has been successfully installed now.

Lync 2013 Logging Tool

After installing Lync 2013 RTM, I noticed that the Lync Logging Tool doesn’t exist.  As you can see below, when you search for the tool under Server 2012, it is missing from the list of Apps.
