What I did to research my previous response was to sign up for an evaluation license for the IntelCompiler SuiteProfessional Edition (for Windows) and clicked through the links to a page that shows the separate tool packages as links. Clicking through any of them takes me to the corresponding product download page. I was successful in this pursuit using IE 6 on a Windows XP box.
