C compilation no working

I'm running Mathematica 9 in a 64 bit Windows 8.1 laptop. I'm having no luck getting C compilation to work.

Needs["CCompilerDriver"]
Compilers[Full]  

returns nothing and

Compilers[]

returns nothing

$Packages shows CCompilerDriver entries

$ContextPath has CCompilerDriver` as its first entry

Microsoft Visual Studio Professional 2013 is installed

Intel Parallel Studio XE for Windows is installed containing Intel C++ Composer XE

Any hints?
