Is Adobe Flash Player ActiveX installed on your computer?

The «Phase» tab of the CSS script display the signal's color scale; in the "Valve timing" tab of the Px script, an animation of the valve timing is displayed. This functionality is displayed using Adobe Flash Player ActiveX. If the ActiveX component is not installed on your Windows, the script will display a corresponding message.

It should be noted that from 31.12.2020 Adobe stopped supporting Flash Player, and from 12.01.2021 it began to block the launch of Flash Player content in current versions of operating systems. In this regard, the display of the color scale of the CSS script and the animation of the valve timing of the Px script are now also disabled. A solution to this problem has not yet been found.
