System Requirements

These recommendations for installing Retail Pro Prism are current at the time of publication; however, the availability of specific hardware and/or software requirements is subject to change without express notification from Retail Pro International, LLC.  These recommendations assume Prism is the only application installed and running, (except for associated database and operating system). Additional requirements may be needed for the associated database, operating system and any ancillary software. Before installing Prism, verify your system meets at least one level (Minimum, Normal, or Ideal) of these requirements.

32-bit not supported for Prism Server
The Prism Server requires a minimum of 4GB of RAM (8GB is preferred and 16GB is even better) and therefore must be run on a 64-bit system. A 32-bit system can only run a maximum of 2GB of RAM.  A 32-bit system could host the browser used to connect to a server, or could host the Proxy, but not the full Prism server.
