Installing the software is the best first step in Getting Started. Installation directions are in the Release Notes.
NOTE Be sure to install Sentinel RMS using the serial number that Thales provided you. The serial number is on a card shipped with the software. If you need to install multiple copies of Sentinel RMS across your organization, use the same serial number in each installation.
The software can be installed without a serial number but then there is no guarantee of uniqueness of the various files used in your licensing implementation.
