Use on Multiple Computers
For your own personal use you may install Songworks 4 on any number of computers, as long as your login (Windows ID or Apple ID) is the same on each. At the first sign-in an online account is created for your name and whenever the program is installed on another computer using the same ID it will automatically connect to that same identity.
What if the internet is down?
The internet is needed for the initial sign-in, which since the program was downloaded in the first place should not be a problem. Once signed in, the internet is not needed unless you want to access the online music library or download an update.
