How to update PowerPoint 2016 to version 16.17
I just bought Office 2016 for my Macintosh and I want to add free Microsoft clip art to a PowerPoint file. My PowerPoint is version 16.16.2. According to a support article (https://support.office.com/en-us/article/add-clip-art-to-your-file-0a01ae25-973c-4c2c-8eaf-8c8e1f9ab530), I should have access to Microsoft's online image gallery, but it requires PowerPoint version 16.17. When I attempt to update PowerPoint, I am informed that no updates are available. So I have no access to Microsoft's online image gallery. Please advise. This is a fully paid and activated product.
