Reinstall Updaters When Necessary
The Problem:
I'm a good citizen, and I've been keeping Office updated. But Word keeps asking me to reapply the Office updaters I've already applied.
The Solution:
Relax, this is normal. You'll need to reapply updaters if you install or reinstall any Office component or if you install options from the Value Pack. Use the Help 
Check for Updates command to keep Word updated with minimal effort on your part.
