问题
I am trying to do some perf. analysis on a piece of code that is dog slow... I start VS2012 Premium as Admin, load my solution and the go to 'Analyze - Launch Performance Wizard' Immediately I am shown a dialog that says:
Could not load file or assembly 'VSPerfReader.DLL' or one of its dependencies.
Awesome! The file is located here:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Performance Tools
I can start Windows Performance Analyzer (standalone) from 'start' just fine btw.

Had the same issue, adding the following line to my system path variable and restarting visual studio did the trick.
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Performance Tools
Credit to Ade Miller in the comment for the solution.

Same instructions as Ryan Taylor above but with a visual. My issue was with Visual Studio 2013 (after installing VS2015 SP1). The value I entered the new path variable is below.
C:\Program Files (x86)\Microsoft Visual Studio 12.0\Team Tools\Performance Tools
