I can for some reason open Powerpoint... any ideas?
From what you posted up it looks like you have the program installed on your desktop, is that correct? Is Powerpoint located in the same place as Word? This could be causing some issues as Yosemite would have reset some of the permission settings on your desktop during the upgrade.
