Users
- The license is valid for one named user (not a location).
Multiple machines

- The person named on the license is welcome to install the program on TWO machines (for example, a desktop and laptop) provided that he/she is the only user of the software.
- Only one "lab computer" per license is permitted. If the program is installed on a lab computer, it cannot be installed on any other computers.
- You will need a separate unlock code for each machine, which we supply at no cost.
