Error code 646 when trying to install Windows updates.

Windows updates appear to download but will not be installed.  I tried to go into 'control panel '; Security systems &; then Windows updates.  It checks and concludes that they are downloaded and try to install but won't.   My computer is set to automatically download and install, so I'm never checked to see if they really were the installation so far.  It seems the latest installations of updates took place the 1/11 & 12/01/11.  There has been many failures last year.  Right now, it seems that there are 6 updates important and 6 optional updates that will not be installed.

I tried to disable my Norton Internet Security and then the installation, but that does not work either.

Can anyone help?

Thank you.
