PowerPoint and Keynote (macOS only) presentations can be imported just like any other piece of media. Once imported, Worship Extreme will launch PowerPoint to create the presentation thumbnails. PowerPoint or Keynote will need to be installed on the computer for this process to succeed.
On macOS, you have the option to use PowerPoint or Keynote to generate PowerPoint thumbnails. Under "Settings" > "Defaults" > "PowerPoint Import", select "Keynote". This is a great option for macOS users without PowerPoint installed. Keynote can be downloaded from www.apple.com/keynote if needed.
If you are seeing a "verify PowerPoint is installed" or "verify Keynote is installed" message and you have either PowerPoint or Keynote installed; verify Worship Extreme has permission to control the application.
