WORKAROUND
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To correct this problem, you must remove the Office settings from the registry. To remove the damaged Office registry settings and re-register PowerPoint, follow these steps.

NOTE: The following steps remove all user-specific settings for all of the Office programs. You must reconfigure all user-specific settings manually.  Click Start, and then click Run. In the Open box, type Regedit and then click OK. Expand the HKEY_CURRENT_USER sub tree until you see the following folders:

'''HKEY_CURRENT_USER\Software\Microsoft\Office\8.0

HKEY_CURRENT_USER\Software\Microsoft\Office\9.0'''

 Delete the 8.0 and 9.0 folders only. Quit the Registry Editor. Quit and restart Windows.</li> After you return to Windows, place your Microsoft Office 2000 CD into your CD-ROM drive.</li> Start PowerPoint. PowerPoint goes through a brief self-repairing routine and then opens normally.</li></ol>

You should be able to open the presentation. However, if PowerPoint does not perform self-repair in step 8, you must repair Office manually.
