Error in Simulink: Invalid MEX-file

HI, I am new to Simulink and trying to simulate a Simulink model. It has a S-Function embedded in it. Along with the model I have several dll files and a mexw32 file. When I try to simulate this .mdl model, I get following error message. Could you throw some light on it as to why it is happening?

"Invalid MEX-file 'C:\Program Files\MATLAB\R2011b\toolbox\stateflow\stateflow\sf.mexw32': The specified module could not be found."

Is it a version change issue?

Thanks in advance

That is a Stateflow MEX-file - it looks like it may depend on some Microsoft Visual Studio redistributables that you are missing. Could you try installing Visual Studio 2010 redistributables and see if that fixes the issue: http://www.microsoft.com/en-us/download/details.aspx?id=5555

Thanks for the reply. I managed to run this simulation in R2010b and could get past this error. Dont know what was happening behind the curtain !

Perhaps you have Visual Studio 2005 or 2008 installed, but not 2010?
