The browser Internet Explorer stops working by saying that I should have a new operating system. What is the reason and what can I do? I have Windows XP Professional.
download the latest IE 8.0 from http://www.microsoft.com/windows/Internet-explorer/default.aspx
You receive that message because the Internet Explorer version you're trying to run is not compatible with your Windows platform. Since you're using Windows XP, I recommend that you use Internet Explorer 8.0. You can download it free of charge from Microsoft Download Center.
