If you still use the ancient Microsoft web browser and see popups like Internet Explorer blocked this website from installing an ActiveX control, this article is for you. Here, you will find relevant information and an effective solution.

ActiveX is an increasingly antiquated software framework that is still utilized within Internet Explorer and other Microsoft applications.

It enables some websites to display interactive content, such as toolbars and games. However, in recent years, this technology has been outdated. Even if you depend on it, you may face many problems like IE ActiveX interface marshaling library won’t open or anything else.

In addition, ActiveX controls can also assist malware in installing unwanted software on Windows.

Consequently, IE automatically blocks ActiveX controls installation. That will happen for users who have enabled the ActiveX Filtering setting.

Then, some content might be missing from a page. When filtering isn’t enabled, users might still see prompts at the top of IE requesting permission to install an ActiveX control.

Quick Tip:

You’ve seen how tricky Internet Explorer’s ActiveX Filtering setting really is, and deselecting it or turning it off for specific websites might not necessarily sound like music to your years.

Instead of wasting valuable time on fixing ActiveX-related errors, install Opera. The first thing to point out is that it never blocks ActiveX controls installation.
