Additionally, you may receive an error message that resembles one of the following error messages:
PowerPoint can't open the type of file represented by path/filename.

PowerPoint can't read path/filename.
Note If you are sure that the presentation was not created or edited in Microsoft Office PowerPoint 2007, in Microsoft Office PowerPoint 2003, or PowerPoint 2002, your presentation is likely to be damaged.

This behavior occurs when you attempt to open password-protected PowerPoint 2007, PowerPoint 2003, or PowerPoint 2002 presentations in any earlier version of PowerPoint or in the PowerPoint Viewer.

PowerPoint 2003 or PowerPoint 2002
