You'll need to sign-up for a trial version of Breeze too to
get the trial version of Presenter. Once you've got your Trial
version, you just need to log-in to the Breeze Manager, go to the
Home tab and click on the Getting Started link to download the
Presenter for PowerPoint add-in.
A limitation though of the trial version would be that it
only allows you to publish to a Breeze server and you would not be
able to publish to your local hard drive.
