Intel Composer XE's C++ compiler does not integrate with Visual studio 2010

We installed Intel Composer XE suites that included Fortran and C++ compiler and both are supposed to integrate with our Visual studio 2010. However, only Fortran compiler shows up in Visual studio and not C++. We tried to installed separately with C++ package only but it still doesn't show up. What happened and how do we get it to work on Visual Studio 2010?

Thanks
