To run ActiveX controls in Internet Explorer, make sure that the browser can download the controls. Open Internet Explorer, click Tools in the menu bar, and select Internet Options. Click the Security tab, click Internet, and click Custom Level. Once there, locate the ActiveX controls and plug-ins section.

For the Automatic prompting for the ActiveX controls setting, select Enable. Select Enable or Prompt for other settings including Download signed ActiveX controls, Run ActiveX controls and plug-ins and Script ActiveX controls marked safe for scripting.

Google Chrome doesn't provide native ActiveX support, but you can run ActiveX control by installing Chrome extensions such as IE Tab. To install IE Tab, navigate to, and click the Try It Now button at the center of the page. Alternatively, click Web Store in Google Chrome, enter "IE Tab" in the Search text box at the upper-left corner of the page, and click Add To Chrome beside IE Tab in the Search Results page. Once installed, click the icon for IE Tab beside the address bar in Chrome to open a new tab that can run ActiveX.

Mozilla Firefox also doesn't offer native ActiveX support. To run ActiveX in Firefox, navigate to, and search for a plug-in called ff-activex-host. Download the setup program for this plug-in by clicking the download link on the left sidebar, and double-click the program to install this plug-in.
