If Simulink is started within MATLAB following error is displayed:

Caught "std::exception" Exception message is: FatalException(unknown) MATLAB:dispatcher:loadLibrary Can't load 'C:\Program Files\MATLAB\R2014a\bin\win64\sl_graphical_classes.dll': Das angegebene Modul wurde nicht gefunden.

. Caught MathWorks::System::FatalException

It worked directly after the installation, but it always fails when Matlab is restarted. I reinstalled the program multiple times. I also added the program to the white-list of my Internet Security Program and start it with administrator privileges.

You should try disabling any security software that may be running on your machine, and attempt to launch MATLAB as an administrator.

If the issue persists you should run a dependency analysis looking for the dll which is causing trouble. For instance this error could be generated by a QT version conflict when the QT version used by another software is different from the one used by MATLAB.

To set up dependency analysis and run it please see the link below:

here you can see also a script that should help you to configure the dependency walker from MATLAB:

Thanks, Sandip, MathWorks

Is this still the recommended procedure? I have the same issue with my recent 2014a install (I did not have this issue with the previous 2013 version). I didn't know if there were new developments before I start.
