Visual C++ 2010 Express is actually superfluous if you only want to use it
as a C compiler for Mathematica or compiling projects from the command
line rather than making use of the IDE; the Windows SDK 7.1 is sufficient
by itself in this case. I think the most likely explanation for the
behaviour you are seeing is that CCompilerDriver realises that the
installation in C:\Program Files (x86)\Microsoft Visual Studio 10.0 can
only produce 32-bit code (a deliberate limitation of Visual Studio Express
and the reason why this does not work with Mathematica on 64-bit
computers), but does not look further to find the 64-bit compilers
installed with the SDK. If so then you can get around it in several ways:
1. Define $CCompiler = {"Compiler" ->
CCompilerDriver`VisualStudioCompiler`VisualStudioCompiler,
"CompilerInstallation" -> path}, where path is the installation path you
have chosen for the Windows SDK.
2. Install the Windows SDK into C:\Program Files (x86)\Microsoft Visual
Studio 10.0\SDK rather than your present choice of installation directory
and let it overwrite the 32-bit-only SDK components installed by Visual
Studio Express. (Admittedly I am not completely sure whether Visual Studio
2010 Express will still work properly afterwards if you do this.)
3. Remove both Visual Studio Express and the SDK and reinstall the SDK by
itself in such a way as it will work with Mathematica. If you like, you
can follow the instructions I gave here:

Whichever approach you choose, don't forget to install the SP1 update:

on this step are included in my instructions linked above.)
