I’m pleased to announce that the Exchange 2013 unattended installation script has been updated and supports fully automated installation of Exchange 2013 on Windows Server 2008 R2 SP1.

The new version contains the following changes:

• Added support for Windows Server 2008 R2 SP1. To fulfill the requirements, code was added to install .NET Framework 4.5, Windows Management Framework 3, disable/enable Internet Explorer Enhanced Security Configuration (IE-ESC), install required hotfixes KB974405, KB2619234 and KB2758857 (which supersedes KB2533623).
• Because of the mandatory reboot after installation of the hotfixes, a phase was inserted; this phase will be skipped when installing on Windows Server 2012.
• Added InstallPath to AutoPilot parameter set (or default path won’t get set).

You can download the updated version of the script via the original Exchange 2013 Unattended Installation Script page (which also contains instructions) or directly from the Technet Gallery.

The script has been tested with Exchange 2013 CU1 but it should work with RTM as well (if you must ..). Your feedback is very much welcomed!

The last version is version 1.53, dated June 15th, 2013; For changes, consult the changelog on the original article or Technet Gallery page.
