Sorry, "C:\...\POWERPNT\PP4X32.DLL" can't be loaded.

-or-

"C:\PATH\FILENAME.PPT" Sorry, this type of file cannot be opened in Microsoft PowerPoint.



CAUSE
This problem occurs when the registry entries for the Pp4x32.dll file are invalid or missing.

 Verify that the Pp4x32.dll file is on your computer.

If the Pp4x32.dll file is not on your computer, rerun PowerPoint setup in maintenance mode and click Reinstall. Verify that the file is correctly registered in the Windows registry:  Exit PowerPoint. On the Start menu, click Run. In the Open box, type "Regedit" (without the quotation marks), and then click OK.

The following table outlines the values that you will find in the registry key if the PP4x32.dll file is registered correctly: <pre class="fixed_text">        Value                    Data -
