Sibelius 7 on a second PC
Install it. You may have to contact the licensing help to get it authorised, but you are entitled to have 2 installations.

You can install it on as many computers as you wish, but you're only allowed to have two active installations at a time. It used to be easy to register and de-register v7 with a couple of mouse clicks, but these days you'll probably need Avid's help. If you ask on the official Sibelius forum, someone will give the email address for Ingrid Guce at Avid, who is usually very helpful!
