Method 3: Remove all Auto-recover files.
One or more corrupted Auto-recover files may be on the system, and may be preventing PowerPoint from opening your presentation.
For PowerPoint 2008:
PowerPoint 2008 saves the file in the Microsoft User Data/Office 2008 AutoRecovery folder with the name "PowerPoint Temp." Move these to the desktop. You can review them later to see if they are important.
For PowerPoint 2004:
If you cannot open the presentation from the Open dialog box, the thumbnail image may be damaged. After you click a presentation in the PowerPoint Open dialog box, PowerPoint displays a thumbnail of the first slide. If this thumbnail is damaged PowerPoint may not be able to open the file using this method. Try a different method.
Method 3: Double-click the PowerPoint presentation.
In the Finder, double-click the presentation file that you want to open.
Method 4: Try to insert the slides into a blank presentation.
Method 5: Try opening the presentation with PowerPoint Viewer.
If you can open the presentation, this may be an indication that your PowerPoint program is damaged or that you have some corrupted objects within the presentation.

In some cases, moving the PowerPoint file to a different operating environment may allow you to open the presentation. If you are able to open the file, search the slides for any blank object place holders and delete them. Re-save the presentation, return the file to its original operating environment, and then try again.
