Fix PowerPoint Animations Not Working After Using Mentimeter Add-in
Question details
Slide animations fail to play in the PowerPoint desktop application when the presentation contains Mentimeter content, despite functioning properly in PowerPoint for the web.

- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Presenting a slideshow with customized animations alongside interactive Mentimeter polls.
- Observed behavior
- Animations stop triggering or playing entirely in the desktop client. Removing the add-in directly from the desktop app does not immediately restore the animation functionality.
Verify that your Microsoft Office suite is fully updated, and create a backup copy of your presentation file before attempting to strip out add-in content.
Recover the Presentation via PowerPoint for the Web
Because the presentation works flawlessly in the web version, you can use it to strip the conflicting content and download a clean copy.
The compatibility issue often embeds itself into the file's metadata when opened in the desktop app. By accessing the file through PowerPoint for the Web, you bypass the desktop add-in environment, allowing you to salvage the animations and download a fresh, uncorrupted version of your slides.
Upload your presentation to OneDrive or SharePoint and open it using PowerPoint for the web.
Locate the slides containing the Mentimeter add-in objects and delete those specific elements from the presentation.
Navigate to 'File', select 'Save As', and click 'Download a copy' to save the cleaned presentation back to your local computer.
Open the newly downloaded copy in your PowerPoint desktop application and test the slideshow to ensure your animations are working.

Update PowerPoint and Add-ins
Ensure that both your desktop software and the specific add-in are running on the latest versions to patch known bugs.
Report the Compatibility Issue
Since this is a known interaction issue between two specific pieces of software, reporting it accelerates a permanent developer patch.
Try WPS Presentation for Flawless Slide Animations
If persistent compatibility bugs and add-in crashes in Microsoft PowerPoint are ruining your presentations, consider switching to WPS Office. It offers a highly compatible, lightweight platform that keeps your slide transitions and animations running smoothly without the heavy overhead.
- 1. Download and Install: Download WPS Office from the official website and complete the installation on your PC or Mac.
- 2. Open Your Presentation: Launch WPS Presentation, click 'Open', and select your .pptx file.
- 3. Present Seamlessly: Click 'Play' to start your slideshow and enjoy smooth, uninterrupted animations.

Frequently Asked Questions
Why do the animations work in PowerPoint for the Web but fail on the desktop application?
PowerPoint for the web processes add-ins and renders animations differently than the desktop client. The desktop environment can sometimes struggle with memory or object rendering conflicts introduced by third-party interactive add-ins like Mentimeter.
Will simply deleting the Mentimeter add-in solve the problem?
Not necessarily. Many users report that even after removing the add-in from PowerPoint, the animations remain broken. You often need to remove the interactive slide content entirely or download a fresh copy from the web version to clear the embedded metadata.
How can I use interactive polls without breaking my animations?
Until a permanent patch is released by Microsoft or Mentimeter, consider presenting your poll in a standard web browser and simply Alt-Tabbing (or using a hyperlink) from your presentation, keeping the PowerPoint file free of complex add-ins.
