Depending on your system and requirements, you can either install Sentinel RMS license server on individual computers or on a single computer that will act as a central license server. A Sentinel RMS license server is installed automatically with your product, and you can choose any machine on which it is installed to act as the central server if required.
You need an appropriate type of authorization code in order to install your license or licenses. For example, if you have ordered 50 licenses then the authorization code installs either 1 license on each of 50 machines or 50 licenses on the central server. If you do not know which type of code you need, contact your system administrator.
