You type the following line in Command window and then follow instructions:
mex -setup

I merely explain that error message to you. Did you run it? What C compiler do you have? MATLAB provides the lcc compiler. What error do you have now when you try to simulate the model? Do you use "Fcn" block, or "MATLAB Fcn" block or "Embedded MATLAB Function" block? You got to be specific and provide more details about your question.

Have a look on the MathWorks web site at the list of supported compilers.
Embedded MATLAB Function blocks use C code generation, and that C code needs to be compiled with a C compiler, so you need to have one installed. As already mentioned, the way to set up the C compiler for use with MATLAB and Simulink (once it's installed on your machine) is to run mex -setup.
For more details, see the documentation about Building MEX-Files.
