The ‘ProviderPackage’ package did not load correctly

I installed Visual Studio 2012 and at a later date Update 2. After installing Update 2, when I load any project, I get the following error:

—————————
Microsoft Visual Studio
—————————
The 'ProviderPackage' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\username\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml'.

Continue to show this error message?

Yes No

After locating the ActivityLog.xml, I see the following set of errors:

Google searches do not reveal an exact match on my issue. I've tried searching the packages on the install ISO and cannot locate a package that needs to be repaired…
