I tried installing from the set of cd's (on my XP pro).  the installation
could not find a file that it needed.  it asked me to retry, browse, or
cancel.  after searching for the file several times, i had to cancel the set
up.  during the rollback of the installation, the uninstall hung.  the
progress bar stopped moving.  i let it sit overnight and decided that it was
a complete loss.

Now i have downloaded the msdn single file version, and tried to install
again.  every time i try to install, the progress bar will freeze at a
certain point in the installation.  any attempt to cancel will result in a
hangup too.

Any ideas?
