Licensing Sibelius
Because Sibelius must check out a license from the UNH license server each time it runs, you must be either on the UNH campus on a wired Ethernet connection or using the secure eduroam wireless network, or you must be connected to the USNH VPN service if using the software from off campus.
Task: To activate Sibelius on your devices
Instructions
Step 1 - The first time you run Sibelius, the program will request that you activate the software. Click the Specify License Server button.
Step 2 - Enter academic.unh.edu as the name of the license server.
Step 3 - Once the license server is setup you will not have to modify the configuration again for this version of Sibelius.
