I've seen similar problems many times. Options are:
1) Wait for MS to issue a new patch that fixes or supecedes the troublesome patch.
2) Uninstall and reinstall Powerpoint (or do a repair install)
3) Next time it pops up select custom install and uncheck the patch that won't install.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
