Use C:\Program Files (x86)\Microsoft Visual Studio 10.0 anyway [y]/n? n

Location: [C:\Program Files\Microsoft SDKs\Windows\v7.1]

Are these correct [y]/n? y

Error: Could not find the 64-bit compiler.  This may indicate that the

"X64 Compilers and Tools" or the Microsoft Windows Software

Development Kit (SDK) is not installed.  To build 64-bit MEX-files

Microsoft Visual C++ 2010 requires that these two packages are

installed properly.
