DemoTools - Hardware Requirements

I cannot see the buttons on the top-right of the "Load" screen

If the program starts correctly, but does not show buttons on the top-right of the "Load" screen, you have probably not maximized the DemoTools Window. Just click on the maximize button on the top-right of the DemoTools window ( in the title bar).

Please note that with the Standard Version of DemoTools you have only one button at the top-right corner of the "Load" screen. It should be labeled "UN-98 data".
With the Professional Version of the DemoTools software you also have a second button (labeled: "Custom data"); and with the Advanced Version you also have a third button for loading the "Lectures".
