I recently installed MS Visual Studio 2013 Professional (update of VS 2012).
I had, and still have VS 2010 installed. Prior to installing VS 2012&2013 I had installed Intel Parallel Studio XE 2015 Pro for Fortran and C++. This integrated into VS 2010 without an issue.
Wanting integration into VS 2013, I (re)installed Intel Parallel Studio XE 2015 Update 2 Professional for Fortran and C++ Windows.
