I have an RFEM license with USB dongle. Can I install and use the program on several computers?


Yes, you can install the program on several computers. During the installation, the driver of your USB dongle is usually installed automatically.

In order to use RFEM on a single computer, simply insert your dongle and start the program.

When opening the program for the first time, it is necessary to import the authorization file AUTHOR.INI (see the figure) to activate the full version on your computer.
