Windows Update and Services up the creek!

Cannot install Security Update for Microsoft .NET Framework, Version 1.1
Service Pack 1 (KB929729) - I tried downloading direct from Microsoft
website after it failed many times through the Start Menu. So online,
when it came to running the installer program I get told that "Windows
Installer has stopped working", I looked in Services in Administative
Tools and looked at the Windows Installer settings, but unlike all the
other services, i was unable to Start, Pause or Restart it..
Also WMI Provider Host has stopped working, I get this Description of
the problem -

... when I click on "Check online for a solution (recommended)",
Windows checks for a solution in the background but this never seems to
bear fruit as the message is constantly appearing.
Would greatly appreciate help with this, thanks in advance.
