If you are reading this guide because you believe Flash is currently installed on your system and causing errors, you should uninstall it immediately.

The "ActiveX component" referred to the specific version of Adobe Flash Player designed for on Windows.

This component is required to run Flash content within Internet Explorer or any application that uses the ActiveX control (e.g., older Windows software, certain ERP/training tools).

If you are looking for the download because you want to view old Flash games or animations, you do not need the ActiveX component.
