Download the Vevox PowerPoint add-in here. This add-in is only available for Windows. 

The Vevox tab is now available in PowerPoint.

Click on the Vevox Tab and click on the Disconnected icon to connect to Vevox.

Select a Meeting to join (this is another name for Session). The Session must be active to be added. (How do I do that?)

Choose the Convert to Slide option from the Vevox menu in PowerPoint.

Please note: You must have the Vevox PPT add-in installed on the computer you intend to run the slides from in order for the live features (e.g. polls) to work.
