Maybe what you can try (before you try points 1..11) only turn Off your antivirus and turn Off UAC, then manually install the updates that failed to installand run Windows update to install rest of updates. Turn On your antivirus and turn On UAC. How turn Off UAC see point 5).
EDIT 8/16/2011
If these steps above not help, try to use these ones:
1) uninstall Net Framework 4.0 client from „Uninstall and change program“:
