Sibelius 6 Network Licences

Technical information

Sibelius's network licenses operate on a client-server model. The Sibelius program itself is installed on the local hard drive of each of the client workstations, and a separate Licence Server program is installed on a single designated server or workstation. The Licence Server program is supplied on a separate CD-ROM from the Sibelius program itself and enables the designated number of licensed client copies to run on the network simultaneously. In conjunction with Sibelius 6's Classroom Control feature, the Licence Server also lets you send messages to users of the client copies, send and receive Sibelius files between client machines, and close copies down from the server machine.

Requirements

Sibelius requires a network using the TCP/IP and UDP protocols. (Your network may use other protocols in addition to TCP/IP and UDP, but TCP/IP and UDP must be present in order for the Licence Server to communicate fully with the client copies.)

The Sibelius Licence Server and the Licence Server Control Panel will run on Windows XP, Windows 2003 Server, Windows 2008 Server, Windows Vista 32 bit, Mac OS X 10.4 or later or on an Xserve running Mac OS X 10.4 or later. It will also run on a virtual server running VMWare using a qualified Windows operating system as listed above.
