Do I need to install the required updates before installing Internet Explorer 9 Beta?
You do not need to download and install the required updates when you upgrade by using the ClickOnce or offline installer. Both installers automatically download and install the required updates. You must download the updates and add them to your Windows 7 images if you are adding Internet Explorer 9 Beta to them, however. You must also add the updates to your Microsoft Deployment Toolkit 2010 deployment share if you add the Internet Explorer 9 Beta update to it.
