Flash Player 184.108.40.206 Causes Corruption in PowerPoint Presentations By Justin Grenier Hi, Everyone. A bug has been identified in Flash Player 220.127.116.11 that corrupts PowerPoint presentations with videos and Flash objects. Until Adobe releases an update to fix it, we recommend staying with Flash Player 18. If you've already installed Flash Player 18.104.22.168, here's how you can downgrade to version 18. If you have a presentation corrupted by Flash Player 19, please follow the instructions here to repair it.
