How to install IE6 and IE7 on same computer

[bkoopers]

I need to test my webpage codes on both IE 6 and IE7 since some html/css code respond differently in these two version of IE. When I installed IE7 in a Windows update, it replaced IE6. How can I install both IE6 and IE7 on the same computer so I will not need two computers to test my webpage code or is this not possible?

Thanks to anyone who can help me out.
