Hi Rob,
There is no reason to uninstall/reinstall Office. This problem has nothing to do with installation failure.
This is a bug in the current update of Microsoft PowerPoint. Uninstall/Reinstall will just give you the same thing you have right now.
You can restore the previous build. Restore Microsoft PowerPoint.app in the Applications folder. Choose a previous month's build.

To prevent AutoUpdate from putting the current version back, use the Menu Bar and choose Help > Check for Updates, which will launch AutoUpdate. Change it from Automatic to Manual updates until this problem has been resolved.
