Multiple IE Versions in Same Windows PC

You  have  installed IE 7 or IE 8 and you want to test your website in IE 6 or earlier ? this post is just for you.

Normally IE (Internet Explorer) doesn’t allow multiple versions to be existed in a single computer. Once you have the latest version of IE installed in your computer, the previous version of IE will be overwritten. It shouldn’t cause any problem to users who use it for surfing net. However, if you are a web developer, then you might encounter inconvenient as you need multiple versions of IE to test out your web application to ensure it works fine without any misalignment problem. With Multipe IE solution, it is possible to run multiple versions of IE in the same computer.

It is possible to run Internet Explorer in standalone mode without having to over-write previous versions thanks to Joe Maddalone who came up with a way of achieving that in November 2003. Basically, Internet Explorer is run by exploiting a known workaround to DLL hell – which was introduced in Windows 2000 and later versions – called DLL redirection.
Manfred Staudinger
perfected the standalone versions by adding IE version numbers to the title bar of the standalone browser window. Moreover, by removing the “IE” key in the registry subkey [HKLM\SOFTWARE\Microsoft\Internet Explorer\Version Vector] Internet Explore defaulted to respecting conditional comments based on the version number prebuilt in the program.

Multiple IE is freeware and it is an executable file which has been bundled with IE 3.0, IE 4.01, IE 5.01, IE 5.5 and IE 6.0 into one package. Once you execute this file, it will install all these versions of IE in your computer at one time. If you don’t want all of these versions to be installed, you can untick any version that you don’t want in the setup screen, then it will only install based on the versions which have been ticked. After installation, you can launch any version of IE as you like fromthe start menu.

  1. What about IE7 and now IE8? Does Multiple IE let you keep installing past IE6? If so how do you do it since the program only goes up to IE6.

  2. if you have IE7 or IE8 installed, you can use Multiple IE …

    but IE7 and IE8 at the same time isn’t possible….. I think it will be possible in future version….

  3. There is another great solution if you need IE 6/7/8 same time on your PC. And it also works on Vista & Seven, here it is:

    Enjoy 🙂
