The programs and files needed by APEX are automatically installed on the PC with the underlying software (A-Shell for Windows or ATE). Starting from the date it is installed, APEX will work in unrestricted mode for approximately 30 days. After that free-trial period, APEX reverts to demo mode, which means that it will work so you can see its functionality, but with qualifications. When operating in demo mode, APEX will display an annoying message saying that it is in demo mode.

To enable full APEX operation on your PC, you will need to obtain an APEX software license from either your application provider/dealer or from MicroSabio.
