Windows installer damaged?? How to repair or reinstall?

I am having problems installing windows updates as well as installing my new trendmicro security.  I believe it is because windows installer is not working correctly.  Does anyone know how to reinstall windows installer or repair it?

My problem was fixed by repairing the registry.  I did not feel comfortable doing it myself in vista (have repaired registry in XP and older OS) - I had an IT person from work do it for me.  I believe that the instructions they are giving you on line will fix it.

Good Luck!
