MATLAB: ‘Make Error’ when starting Simulink simulation

make error simulink sfunsimulink

I am getting a Make Error with the following message: Making simulation target "DP_ForceRAOnew_sfun", …
C:\Users\Michael\Dropbox\Codes\MSS\hydro\simulink\slprj\_sfprj\DP_ForceRAOnew\_self\sfun\src>call "\vsvars32.bat" '"\vsvars32.bat"' is not recognized as an internal or external command, operable program or batch file.
C:\Users\Michael\Dropbox\Codes\MSS\hydro\simulink\slprj\_sfprj\DP_ForceRAOnew\_self\sfun\src>nmake -f DP_ForceRAOnew_sfun.mak 'nmake' is not recognized as an internal or external command, operable program or batch file.
Within the simulink model I have a M function that performs a dos command to run a executable. Could this be the source of the error?
Regards

Have you already installed a supported compiler (see last column on this page for the list against each version), and run "mex -setup"? It just seems like Simulink cannot locate a supported MEX compiler, which is needed to compile code generated from Stateflow charts or (Embedded) MATLAB Function blocks.
