MATLAB和C语言混合编程，mex -setup怎么执行 不了

菜鸟一枚，求哪位大神帮帮忙。
就输了一句话，就出现了这个错误提示，但是不知道怎么解决

mex -setup
MEX 配置为使用 'lcc-win32' 以进行 C 语言编译。
Warning: The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the
new API. You can find more information about this at:

要选择不同的语言，请从以下选项中选择一种命令:
mex -setup C++
mex -setup FORTRAN
警告: Windows SDK 7.1 appears to be installed, but its compiler was not found. Install .NET Framework 4.0,
and then rerun the SDK installation to add the "Visual C++ Compilers" component. See
