If the requirements in the template stated that you needed to install the Exchange Management tools on the Orion server than you're using an old version of this application template. My recommendation would be to delete this template entirely from your Orion server and download the latest version available here on Thwack -> Exchange 2010-2013 Database Availability Group
You can even download this template from within SAM by going to the "Shared Templates on Thwack" under [Settings -> SAM Settings -> Shared thwack Templates].
