Dear Mr. Muzaffar,
I think that you have to make some changes in the "configuration parameters" [in simulink, go to Simulation (left upper side of the screen) --> configuration parameters]. Perhaps you have to make some changes in the "solver" part (only expecting but I don't know exactly the problem). Is the MATLAB installed completely???
Mr. Abdel, i have this error while i run the simulation :
The specified configuration type is missing. The tools for the
configuration might not be installed.
'nmake' is not recognized as an internal or external command,
operable program or batch file
