MATLAB: Do I receive an error message about pathdef.m when I try to install the Mixed-Signal Library

MATLABmslpathdefsavepathsimulink

I downloaded the Mixed Signal Library from the MathWorks website.
When I try to run the install script to install the library, I get an error message that says that MATLAB is unable to write to the pathdef.m file.

The error indicates that your user account does not have permission to write to the pathdef.m file, or the folder that it is located in.
You will need to insure your account has permission to write to the pathdef.m file, or you will need to use an account that has permission to write to the pathdef.m file to install the software. Contact your local system administrator for assistance with permissions.
The pathdef.m file can be located by running "which pathdef.m" in the MATLAB command window. By default, it will be in:
$MATLAB_ROOT\toolbox\local\pathdef.m
