解决方案

When I attempt to open help from the VS2012 it launches Microsoft Helper Viewer 2.0 but generates an error.

Below is the error from the event log.  From IE I can access the same page (http://services.mtps.microsoft.com/ServiceAPI/catalogs/VisualStudio11/en-US) without any errors.

An error occurred while checking for updates: Microsoft.VisualStudio.Help.CacheLib.CacheLibServiceApiException: The web server has reported an error for http://services.mtps.microsoft.com/ServiceAPI/catalogs/VisualStudio11/en-US: ProtocolError/ProxyAuthenticationRequired
