ActiveX controls are applications in your Web browser that allow you to download files and interact with tools and features from various websites. If you need to enable the application to access the ActiveX features, you can do so through your Internet Explorer security settings. The settings allow Internet Explorer to automatically enable ActiveX website controls or offer a prompt to accept the ActiveX control when visiting a website.
Open Internet Explorer and select "Tools" from the menu at the top of the browser. Choose "Internet Options" from the drop-down menu.
Go to the Security tab in the open window and click "Custom Level." Scroll through the settings list and find the group of settings under the title "ActiveX controls and plug-ins."
Click "Enable" or "Prompt" under "Download signed ActiveX," "Run ActiveX" and "Script ActiveX controls." Click "Enable" under "Automatic prompting for ActiveX controls" if you'd like the system to prompt you before a website installs an ActiveX control.
Click "OK." Restart your computer to enable the changes.
Fully enabling ActiveX controls could allow viruses and other malware to enter your computer. It is highly recommended that you visit only sites you trust, or use the prompt feature when using ActiveX.
