Windows users: ensure that the OPENSIM_INSTALL_DIR/bin directory (e.g., C:/OpenSim 4.0/bin) appears in your system PATH environment variable, and that it appears before any other OpenSim installations you may have on your PATH.

If the script did not succeed, read the output in the command window for more information.

When the script finishes, you should see a dialog box notifying you if the script succeeded.

On Windows, by default, this is C:/OpenSim 4.0. The script will prompt you to choose your OpenSim installation directory (we will refer to this as OPENSIM_INSTALL_DIR).

Run the configureOpenSim.m file from the current folder.

On Windows, by default, this is C:/Users//Documents/OpenSim/4.0/Code/Matlab.

Change your Current Folder to the OpenSim Matlab Scripts directory.

If you're using Windows and you have OpenSim 3.x configured with Matlab, make sure to 'Run as administrator' (available by right-clicking the MATLAB application in the start menu, etc.). As noted above, OpenSim 4.0 requires 64-bit Matlab. These instructions assume that you've already installed OpenSim version 4.0 or later (see Installation Guide for more info).
