I'm that engineer. I just worked through the problems today. There are
two problems with some editions of the CD supplied by AT&T. First, it
has buggy detection for Macromedia Flash and will continue telling you
to install Flash even if it's already installed. Second, it has flags
set that will cause Outlook support files to be installed, but not
Outlook itself. Fortunately, this is fixable on the fly, if you can
successfully bring up the selection page (which is well-hidden). I
never could get around the Flash problem, which meant that the user
interface for installing necessary software was broken and all the
software had to be installed manually.
