PowerPoint – How to see TOTAL run time after creating slide show

Late reply, but here's another possible workaround:

Go to: Slide Show, check "Use Rehearsed Timings, then click on "Rehearse Timings", then, during rehearsal, right after the end of the first slide, click as soon as you wish to make the second slide appear, then save changes for your rehearsed timings.

There's an Add-in you can download that will give you what you want. Seeing that you have the first part setup, you can use this Add-in to display the elapsed time on top of the current slide.

There are installation instructions on the website I have linked to, but for convenience I will include them here.

1. Download the executable and let it install the add-in to the default location. I've scanned the executable and the installed Add-in files for viruses and I can confirm that they are clean.

2. Once the Add-in has been installed, open PowerPoint and do the following:

File -> Options -> Add-ins -> (From the Manage drop-down at the bottom) select PowerPoint Add-ins and Go

3. On the resulting dialog do the following:

Add New -> select TM PowerPoint Timer (Ribbon UI) -> OK

The above will add a TM tab to the PowerPoint ribbon. On the configuration window for the Timer you'll be able to set a timer to show the Elapsed time. There's also an Update Display entry on the first tab, so make sure you set that to 1 second (the default is 10 seconds).
