You can embed a link in your PowerPoint presentation to click on while presenting to open the browser with the results (live) view. In order for this to work you must have logged-in to your administration panel before you start your presentation. That browser will then stay logged-in while it is open.
Unfortunately there is a bug in Microsoft Office which results in always displaying the login screen even though the browser is logged-in. Microsoft provides a fix for this which can be downloaded here:
Download the tool and execute it on the computer running your presentation. Then the link in PowerPoint will lead directly to your results screen.
