Browser Compatibility Check for Internet Explorer Versions from 5.5 to 10

IETester is a free (both for personal and professional usage) WebBrowser that allows you to have the rendering and javascript engines of IE10 preview, IE9, IE8, IE7 IE 6 and IE5.5 on Windows 7, Vista and XP, as well as the installed IE in the same process.

This is an alpha release, so feel free to post comments/bugs on the IETester forum.
Requirement : Windows 7, Windows Vista or Windows XP with IE7 minimum (Windows XP/IE6 config has some problems and IE8 instance do not work under XP without IE7)
Note for IE10 : IETester installer does not include IE10 files, so you will need to install IE10 preview and copy files manually : See How To install IE10 under IETester (IE10 Preview requires Windows 7).

Download IETester v0.4.11 (38MB)
(IETester v0.4.11 zipped installer for people unable to download .exe files due to proxy limitations)
