Microsoft April 2011 update Breaks PowerPoint 2003

[Rick_G]

Most Powerpoint presentations no longer load - you get an error message:

"PowerPoint was unable to display some of the text, images, or objects on slides in the file, "XYZZY.ppt", because they have become corrupted. Affected slides have been replaced by blank slides in the presentation and it is not possible to recover the lost information. To ensure that the file can be opened in previous versions of PowerPoint, use the Save As command (File menu) and save the file with either the same or a new name."

To fix this, you need to uninstall that update, which is "Security update for Microsoft Office Powerpoint 2003 (KB2464588)".

For Windows 7, go to Control Panel / Programs and Features. On the left pane, click on "View installed updates". Then you can locate the update - select it, then click on "Uninstall" near the top of the window"

For Windows XP, go to Control Panel / Programs and Features. At the top of the window, click on "Show updates", and wait a minute. Then you can locate the update - select it, then click on "Remove" near the right side. You may have to insert the original Office 2003 CD to uninstall that update.

I have attached a PDF with screen shots that show what this looks like for both Windows 7 and Windows XP.
