IE6 + IE7 on a clean XP install

Question

We need to test a website in both IE6 and IE7. We've had bugs appear running on actual windows machines that aren't visible under vmware (?!), so we have an actual windows laptop to do this - but only one. Is it possible to install IE6 and IE7 side-by-side in such a way that they absolutely, positively, behave exactly like they would if there was only one of them? How?

Answer 1

The officially sanctioned way is to use the microsoft-provided Virtual PC installation and VPC images. You don't need additional windows licenses to run these.

Answer 2

Take a look at http://tredosoft.com/Multiple_IE. Bear in mind that running both side by side is not supported by Microsoft (http://blogs.msdn.com/cwilso/archive/2006/02/01/522281.aspx) and there's no guarantee that they will work absolutely fine side by side - a Windows Update could easily break something and sometimes people find conditional comments don't work properly amongst other things. All I can suggest is you give it a go and see how you get on.
