We no longer supply the HASP hardware keys (dongles), but if you still have one and are setting up a new system, you will need to install the device driver.
For Windows, run the EXE file to install the HASP device driver. You may need to reboot after the install to make sure that the driver is running correctly.
For Linux, first try the cross-platform installer script; instructions are inside the TGZ file. If that fails, use the Fedora or Suse installers for those systems, or grab the older Linux driver files for all other systems.
For OS X, download and open the disk image for further instructions.
After installing the driver, plug in the dongle; when correctly installed, it will glow red.
