The single-user license is activated using a USB dongle. The software can be installed on more than one computer, but can only be used on a computer that has the dongle inserted, and therefore, on only one computer at a time.
If you want to continue working on a different computer than the one you are currently using, you can save and export your project package and copy it to another computer. By closing the program and removing the dongle, you can insert it into another computer and easily continue working on your project.
If, however, more than one person must be able to work simultaneously, it is necessary to purchase additional single licenses or a multi-user license.
A single license offers you the utmost flexibility; the USB dongle can travel with you and be used anywhere on the go (for example, with a laptop).
