Installing NoteBook on Additional Computers
 
You can use your license key to install NoteBook on as many computers as you like.  The only restriction is that the number of running copies of NoteBook cannot exceed the number of available license tokens.
 
If you have a desktop and a laptop, for example, you can install NoteBook on both computers.  If your license key only contains one license token, you have to quit NoteBook on the desktop before launching it on the laptop.
