I would not recommend the VS Express version. Instead use the "Microsoft 
Windows SDK for Windows 7 and .NET Framework 3.5 SP1" 
<http://www.microsoft.com/en-us/download/details.aspx?id=3138>, which 
contains compatible 32 and 64 bit compilers for Python 2.6 to 3.2. Use 
the web installer or mount the ISO with VirtualCloneDrive 
<http://www.slysoft.com/en/virtual-clonedrive.html>. Then, on a command 
prompt in the numpy source directory type (not tested, but should work 
for 64 bit Python 2.7):

setlocal EnableDelayedExpansion
call "%ProgramFiles%\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.Cmd" 
/Release /x64 /vista
C:\Python27\python.exe setup.py build
