Visual C console application example in HIL simulation using xPC target

I am trying to run the sf_car_xpc Executable. Document says to open a dos prompt and go to the path C:\matlabroot\toolbox\rtw\targets\xpc\api\VisualC

on executing the using command sf_car_xpc -c 0 application it should give following window,

------------------------------------------------------------- * xPC Target API Demo: sf_car_xpc. * * Copyright (c) 2000 The MathWorks, Inc. All Rights Reserved. * ------------------------------------------------------------- Application sf_car_xpc loaded. SampleTime 0.001 StopTime: -1 R Br Th G VehSpeed VehRPM - ---- -- - ---------- --------- N 0 0 0 0.000 1000.000

But instead it given error saying,

The application or DLL C:\program Files\MATLAB\2013b\toolbox\rtw\targets\xpc\api\VisualC\xpcapi.dll is not a valid image. Please check this against your installation diskette.

Please let me knoe hoe to overcome this error
