The single-user license allows exactly one user to use Automation Studio at any given time for a period of one year. The license is stored on a Technology Guard (dongle). This permits multiple users to share the right to use Automation Studio on different workstations by connecting the Technology Guard with the single-user license to the respective workstation computer. The license is not automatically after one year and must be reordered. Technology Guard 0TG1000.02 is included in the package. See the EULA: www.br-automation.com/eula.
