MATLAB: Codegen build error on Windows

codegenmatlab coder

I am using codegen for the first time, following the instructions given here. My function is for simple addition of two numbers (as shown in screenshot below)
Why am I getting the error?
I also saw this link. This is the output I got:
>>  !echo %SystemRoot% 
C:\Windows  
>>  !echo %Path%
C:\Program Files\MATLAB\R2013a\bin\win64;C:\opencv\build\\x64\vc10\bin;E:\Xilinx\Vivado_HLS\2014.2\win64\tools\opencv
Is there anything I have to change?

It appears that your system path does not include the directories where some Windows applications are installed. Is the Path environment variable being edited anywhere anywhere? This could be either via the Windows system menu, or even using the MATLAB function setenv.
My system path includes:
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;
and when I search for cmd.exe I get:
>> !where cmd.exe
C:\Windows\System32\cmd.exe
so adding these directories should help you move forward.
It is probably advisable to search for "Windows default system path" to see what the default system directories are for your version of Windows and make sure those are present.
