System Center 2012 Unified Installer is a utility designed to perform new, clean installations of System Center 2012 for testing and evaluation purposes only. If you want to upgrade from an existing System Center installation or choose set up options such as high availability or multi-server component installs, please refer instead to the System Center 2012 component installation guides located on the Microsoft Private Cloud Evaluation Resource Page.

Before you begin with the Unified installer, you have to extract the installation files of the products. In this example I did that for Orchestrator 2012.
That was easy to use, Cheers!
