Can I install RealFlight on more than one computer?
Under the terms of the Limited Use Software License Agreement, one copy of RealFlight is licensed for one user. While RealFlight is licensed for one user, that user can definitely have it installed on more than one machine at a time. There is no need to deregister a computer.
In the event the user is not able to activate or register on a second machine, they can contact Software Support to request a registration reset for their number. This will allow them to re-register from the new computer.
