To install the program make a new directory on your hard disk and then unzip the downloaded file into this directory. Then run the Setup program. For Windows NT and Windows 9x, Windows Installer must previously have been installed on the machine, otherwise the program will not install. Windows Me, 2000 and XP all have Windows Installer as part of the operating system. Please note that additional drivers are necessary to access the hardlock dongle. These can be downloaded separately from the Drivers section of the software download area.
