• 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.

• Receive error messages when trying to install McAfee and it said their support that the question is related to the error in Device Manager.

  How can you diagnose errors in Device Manager

  Tried installing McAffee, but error message. Contacted McAfee... says the problem is in the Device Manager. How can I determine the error in Device Manager?

  Are you sure you don't have another Antivirus always installed; even an expired subscription?

  A lot of AVs will not install if they find one already installed (and you must have an AV installed in any case).

  Another problem may be how you try to install it:

  You need to download and save on the desktop > then right click on the saved files > select run as administrator.

  FYI: Here's how to look in the Device Manager:
