But there is a problem. Windows allows only one version of IE in a PC. If you install a new version of IE, Windows automatically removes the older one.
To solve this issue, the guys at Tredosoft came up with a installer called Multiple IE that bundles IE3, IE4.01, IE5, IE5.5 and IE6. Just download it and after installing, you should get ready to use start menu shortcuts as shown.
Note: Multiple IE doesn’t work in Vista. It works properly in Win XP and with certain tweaking in Win 2000.
Those wishing to use IE 7 in portable mode or standalone mode should visit this link. There is also another portable version of IE 7 here. There is also a similar portable version of IE 8 beta that you know more about here.
