The AutoCAD 2010 system requirements say that IE7 or later is required. However, I created a 32-bit deployment for AutoCAD 2010, and unchecked the IE requirement box, then installed on a machine with IE6, and AutoCAD 2010 runs just fine.
I know, IE6 is pretty old, but some people still run other software that won’t run on anything newer than IE6.
I have not tried running an install right off of the media, but I suspect it may stop on the IE7 requirement.
