SharePoint Server 2016 Prerequisite Downloader

This script will download all prerequisites that are required for the installation of SharePoint Server 2016 on Windows Server 2012 R2.

For details, see https://www.itunity.com/article/automatically-download-sharepoint-server-2016-prerequisites-powershell-script-3164

It stores prerequisites in three folders:

• A folder for SharePoint Server 2016's prerequisites.

  These prerequisites can be used for offline installation of prerequisistes by PrerequisiteInstaller.exe.

  Use PREREQUISITEINSTALLER.EXE /? for syntax.

  See https://technet.microsoft.com/EN-US/library/ff686793(v=office.16).aspx for details

• A folder for the updates to Windows Server 2012 R2 that must be applied before you can run PrerequisiteInstaller.exe

  I will be uploading a script that applies these updates in the correct order.

  Until then, please note that the Windows Server 2012 R2 updates must be applied in this order:

  • KB2919442 (restart required)
  • clearcompressionflag.exe
  • KB2919355
  • KB2932046
  • KB2959977
  • KB2937592
  • KB2938439
  • KB2934018

  See https://www.microsoft.com/en-us/download/details.aspx?id=42334 and https://support.microsoft.com/en-us/kb/2919355 for details

• A folder for updates that are necessary only in certain scenarios, including Silverlight and Exchange Web Services Managed API.

To modify this script for your environment:

• Create the folders to which updates and prerequisites will be saved
• Modify the values in the CONFIGURATION BLOCK section
• Run the script in a PowerShell console (or ISE) launched with the RUN AS ADMINISTRATOR option

3/21/2016 - Optional updates (Silverlight 3 and Exchange Web Services Managed API) downloading to a non-existent folder. FIXED.
