License Server > System Requirements

## System Requirements

The computer hardware market changes rapidly and, as a result, information about minimum and recommended system requirements also changes. Please refer to the technical notes published on the Support area of the web site for the most up-to-date specifications.

### Server Computer

The License Server may be installed on either a Macintosh or Windows computer. It is a cross platform server; both Windows and Macintosh computers may log on to it.

The license server prefers a system with the following specification:

Processor | Macintosh G5 or Intel processor | Any Intel Pentium 3 CPU or higher Any AMD Athlon CPU or higher Note: Intel Pentium or AMD K6/K6-2 CPUs of any speed are not supported.
Operating System | Mac OS X 10.5.8 or higher (Mac OS 9 is not supported) | Windows 7 Windows 7, Windows XP, Windows Server 2003 (Windows 95/98/ME or Windows NT 3.1/3.5/4.0 are not supported)
RAM | Apple recommends a minimum of 128 MB RAM to run Mac OS X | 32 MB minimum, 128 MB preferred
USB Port | One free USB port required for installation of dongle. A USB expansion card may be purchased for computers without inbuilt USB.
Free hard disk space | 50 MB minimum, 100 MB preferred

The server computer must be set to ‘never sleep’ and must be unlikely to be switched off.

The server computer may also act as a client running one of the applications. If the server computer is to also act as a client, the specification must be as for the client application.

Installation of the License Server can only be performed using an account on the computer with administrator privileges. However, users of Volocity, Openlab or the License Server Administration client do not require administrator privileges on the network to connect to the license server.

### For Mac OS X Systems:

The License Server for Mac OS X is implemented using a daemon. A daemon is a program which runs without any user being logged in. The License Server daemon starts automatically every time the machine on which it has been installed in turned on. The machine can be used for other programs while the license server is running (the License Server takes little processing power or network bandwidth)

### For Windows Systems:

The License Server for Windows is implemented using a service. A service is a program, which runs in the background even if no other user is logged in. The PerkinElmer Imaging License Server service automatically starts every time the machine on which it has been installed is turned on. The machine can be used for other programs, while the license server is running (the license server takes little processing power or network bandwidth).

### Network

The License server uses TCP/IP to communicate between the server and the client.

The client computers must be able to contact the server using IP.

The server must have a static IP address.

By default the server uses port 15002 for TCP/IP communication with clients, although this can be changed in the server application.

By default the web server for the administration tool uses port 15003 for HTTP communication with browsers, although this can be changed in the server application.

Communication between the server and the clients software for which it is serving licenses is encrypted.

The License Server does not generate much network traffic. Requests for licenses are sent from the clients and permissions are returned from the server.

### Client Computers

Macintosh and Windows clients can be served by the Imaging License Server. The system requirements for a client computer depend on the type of application that that computer will run. For example, the requirements for a computer running Volocity Visualization will be greater than the requirements to run Volocity LE. Please see the manual or technical note for the individual product. For example:
