Simulink Rsim executable libmx.dll missing

I want to generate a standalone executable for a Simulink model using MATLAB 2010b 32-bit. My ultimate aim is to have a stanalone executable of a package of M-scripts, GUIs and a simulink model with tunable parameters.

I have tried generating an exe using the Rapid simulation target. It works when I call it from Matlab using

!Modelname.mdl

command. If I run the exe file outside MATLAB, i get the error message

"The program cannot be started as the libmx.dll is missing from the computer."

I have checked and all the required DLLs exist in my system at the path: "C:\Program Files (x86)\MATLAB_Runtime_v7141_r10bSP1\v7141\bin\win32".

Are Rsim executables not meant to be used outside MATLAB? Should I be using the deploytool? I'd appreciate any help.

1. The DLL is located in MATLABROOT/bin/win32. Add this location to the system environmental variable "Path".

2. This error may also indicate that the file "libmx.dll" is missing from your MATLAB installation directory. This can occur if certain antivirus software is installed and it quarantines the file. To resolve the issue, open the antivirus software and restore the quarantined file "libmx.dll".

The purpose of creating Rsim executable is to allow using the model on many computers without needing Simulink. But, if you are pointing to necessity of a DLL from MATLABROOT, then that purpose is defeated.

I searched my entire antivirus program folder.

i didn't find " libmx.dll" file in that folder.

please help me iam lagging of my final year project

Sri Lakshmi did you find a solution? I have the same problem.

The DLL is actually in MATLABROOT/bin/win64 for me
