Cause
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 2002 was the first version of PowerPoint for Microsoft Windows to implement password protection for presentations. Because earlier versions of PowerPoint do not have this capability, they are unable to open any password-protected presentations.

To work around this issue, follow these steps, as appropriate for the version of PowerPoint that you are running:


PowerPoint 2010

  1. In PowerPoint 2010, open the presentation, type the password, and then click OK.
  2. Click the File tab, click the Info tab, click Protect Presentation, and then click Encrypt with Password
  3. In the Encrypt Document dialog box, delete all the text in the Password box, and then click OK.


PowerPoint 2007

  1. In PowerPoint 2007, open the presentation, type the password, and then click OK.
  2. Click the Microsoft Office Button, point to Prepare, and then click Encrypt Document.
  3. In the Encrypt Document dialog box, delete all the text in the Password box, and then click OK.

PowerPoint 2003 or PowerPoint 2002

  1. In PowerPoint 2003 or PowerPoint 2002, open the presentation, type the password, and then click OK.
