I could compile the example in matlab documentation with VS2010. Even for the data tracking code, the mex file was compiled successfully with VS 2010. But when it was called by the objective function I get this error message.

Dear Nicos, Thank you very much for your prompt reply. I also encountered the same issue earlier and modified the OpenSim Install directory. I changed the model name in the cpp code. Still I get the same error. I tried with VS 2015 (enterprise). But Matlab did not recognize it for compiling MEX file...

Dear Nicos and Aaron, I am also trying to run the same code. I got the following error message. Invalid MEX-file 'F:\Research\OpenSimS\DataTracking-latest\DataTracking_Ver1\DataTracking_Ver1\Models\calcStateDerivsMetaPowerFGContactF.mexw64': A dynamic link library (DLL) initialization routine failed...

Dear Dimitar,
Thanks for the information. I am creating MEX file with code from one of the SimTK projects. I got the following error.

Invalid MEX file. A dynamic link library (DLL) initialization routine failed.

I use OpenSim 3.3 and Visual Studio 2010. What are the possible causes for this?

Thanks for the information. Should I mention the name of the path actuator in the <muscle_list>(i.e <muscle_list> Actuator_r<muscle_list>)? When I did that I did not get the results. It gave a file only with time steps, nothing else.

Dear All,
Can I compile MEX file using Visual Studio 2010 and OpenSim 3.3? OpenSim 3.3 is built with Visual Studio 2013.
Thanks & Regards,
Karthick.

Dear All,
How to get the moment arm and moment of a path actuator during a CMC analysis?

Thanks & Regards,
Karthick.

Thanks. It helped to fix the error. Also thanks for the tip for searching the forum for error messages.

Thanks for your reply. Yes. I had multiple versions in the system path and I removed the older versions from the path. Now I get the following error. Error using simpleOptimizerExample (line 31) Java exception occurred: java.io.IOException: Object: ERR- Could not open file testData\Arm26_Optimize.os...
