To install ActiveX on Windows XP, adjust ActiveX Settings in Internet Explorer or install ActiveX on a case-by-case basis while visiting certain websites. To do the former, launch Internet Explorer, navigate to the Tools menu, and click Internet Options. Once the Internet Options window appears, go to the Security tab, and click the Custom Level button.
Once the Security Settings window appears, scroll down the list of settings until you arrive to ActiveX Controls and Plug-ins. Click Enable for the Automatic Prompting for ActiveX Controls option. Scroll down to Download Signed ActiveX Controls and select Enable or Prompt, then scroll further down to Run ActiveX Controls and Plug-ins, and select Enable or Prompt. Scroll again to Script ActiveX Controls Marked Safe for Scripting, and click Enable or Prompt. Click OK, then click OK again to close the windows.
To install ActiveX on specific websites, navigate to the website that requires you to install the ActiveX control and then check the description for a detailed explanation on why you should install the ActiveX control on the website. If the website is reputable and the explanation is trustworthy, check whether the website is the publisher and the provider of the ActiveX control. If it is, accept and run the ActiveX installation.
