Apart from downloaded and installed software and the licence key (in the email sent to you after purchasing the licence) you need to have a USB dongle (pendrive). To activate the portable USB licence you should connect the pendrive to the computer in the moment of activation. Then the pendrive is remembered by our licence server and serves as the hardware key. It means that you need to connect the pendrive each time you want to use the software. Remember that Cubic Orb does not provide you with the pendrive. You use your own.
