  Hi DJMac129,

  We recommend that you run Microsoft fix it in the next article, and then try to install the updates.

• Windows Update encountered an unknown error code 6b 7.

  What is said for the most part.  I am running Vista Home Premium x 64 on a machine rather top of range (Q9550 processor, 16 GB DDR2-800 RAM, fast hard drives 1.5 TB each, etc.) -specs factory, not overclocking, or something like that.  When I try to install the updates, Windows meets an 'unknown error' (Code 6B 7).  It usually happens when he tried to update .NET - and that's why I can't use Windows Live Messenger or all the other Windows Live programs, in addition to a lot of third party programs.

  I am really lost and don't know what to do.  I asked before and told to uninstall and reinstall all the old versions of the .NET, but also warned that the process was dangerous and could cause trouble.

  Thank you in advance for any help you can offer.  If you need more information, please ask and I will answer as best as possible.

  * Title *.
  Windows Update encountered an unknown error code 6b 7. (will not install .NET 3.5 or above, which prevents the installation of a lot of other things)

  I suggest that you run the following tools:
  Disk error checking

  System File Checker

  In addition, the tools above do not correct the problem, you should look at thisarticle.  If it applies to your version of Vista so I suggest try download it see if it will install.
