I want to download the new Internet Explorer security patch at:http://www.microsoft.com/windows/ie/...29/default.asp - but im not sure which one I should download! lol

It asks me if I would like to download either:

Internet Explorer 6 SP1

Internet Explorer 6 SP1 for Windows XP SP1 64-bit Edition

Internet Explorer 6 for Windows XP

I'm currently using Windows XP Home (Version 5.1.2600) & Internet Explorer 6 (Version 6.0.2600.0000)

So which one should I download? And whats the difference?
