Symptoms

The black pearl manager installation completes, but errors for my Visual Studio 2012. The error log reads "c:program files (x86)common7IDEdevenv.exe.config not found"
 

Diagnoses

When the repair tool is ran it reaches out and gets the information from the registry and sometimes has issues when grabbing the .dll
 

Resolution

Fixed the issue by fixing my Environment variables. I've attached screenshots.

Start --> Computer (right click select "Properties") --> Advanced system settings --> Advanced Tab --> Environment Variables

My "VS110COMNTOOLS" variable was missing some characters. It must have happened in one of the installs or uninstalls. The proper value should read "C:Program Files (x86)Microsoft Visual Studio 11.0Common7Tools"
