Can't see Intel C++ in VS 2013

I work on two projects one in VB.NET and one in C++.

I have Microsoft Visual Studio Professional 2013, which I use for the VB project, and Codelite with the GNU C++ compiler, which I use for the C++ project. For various reasons, I want to keep the C++ project free of Microsoft-specific influences.

I wanted to try the Intel C++ compiler, so I downloaded the trial version of "Intel® Parallel Studio XE for Windows" and installed it, and there are now signs of the presence of Intel C++ in VS 2013, but I can't start an Intel C++ project because VS defaults to Microsoft C++.

How do I get round this?
