I guess a couple of questions:
If you look at Windows update, do the updates show as a successful install?
If you go to "Programs and Features" in control panel and click on show updates, do the updates appear to be there?
Maybe if you uninstalled them if they do show up, the could you reinstall correctly.
There is also a troubleshooter if you look in Help and Support
If you have an anti-virus or spyware, you might want to try turning that off.
