error while using embedded function block

i am using embedded system block for a simulink model.. When i am running the file it is showing the following error

"Unable to locate 'mexopts.bat', and therefore cannot determine which compiler to use for simulation builds. Use 'mex -setup' to select a supported compiler."

I checked the command " mex -setup". but there i am not getting the choice of compilers .Following messages are coming

" mex -setup Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler:

[0] None "

 0

mex: No compiler selected. No action taken.

Can you check on your matlab path inside MATLAB\RXXXXx\sys that directory lcc exists or not ?

Lcc compiler comes inbuilt with Matlab.

Lcc is only available for 32 bit operating system. If you are using win64, your best bet is to install Visual C++ Express.
