If you are an serious Web Developer or a Web Designer, you might need to have multiple popular and moderns web browsers like Internet Explorer 6, Internet Explorer 7, FireFox and even Opera, Safari in order to make sure you have created a accessible website and cross-browser supported.

  1. Here is how to get IE6 work on your computer which have IE7 installed http://tredosoft.com/Multiple_IE.setup2
  2. In case you're running IE6 and want to have IE7, check out  http://tredosoft.com/IE7_standalone.

Note that just work in NT5-based Windows like Windows XP, Windows 2003, it might work on Windows 2000, but I have not try it yet.

If you're running Windows Vista, surely IE7 have already installed and the are not compatible on Vista, you might try this one http://tredosoft.com/IE6_For_Vista_Part_1
