I am trying to generate the C code from simulink, but i am stuck with an error which is stopping the generation of C code. The error is :

Error using ==> issue_inv_comp_env_val_error at 9
"Invalid setting for environment variable MSDevDir or DevEnvDir. The setting is: '' You can verify the setting by checking for the existence of: %DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 9.0) %MSDevDir%\..\..\vc98\bin\vcvars32.bat (for Visual C/C++ 6.0) %DevEnvDir%\..\tools\vsvars32.bat (for Visual C/C++ 8.0)
You must define MSDevDir or DevEnvDir to be: set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 9.0) set %MSDevDir%=<VisualRoot>\common\msdev98 (for Visual C/C++ 6.0) set %DevEnvDir%=<VisualRoot>\common7\ide (for Visual C/C++ 8.0)
This error may be due to an invalid preference file: C:\Dokumente und Einstellungen\FGLuser\Anwendungsdaten\MathWorks\MATLAB\R2010b\mexopts.bat Please run "mex -setup" at the MATLAB prompt to correct"

I tried creating the mex -setup at matlab prompt but could not solve my problem... I am not understading why this problem exists... Can any one help me in solving this. Thanks in advance for reply..
