I am an intern working at a fairly large organization, and I've recently been given access to a multiuser computer with matlab on it to perform my work. Upon startup, I am met with the following message.

C:\Program Files\MATLAB\R2015a\toolbox\local\pathdef.m: Cannot open file: permission denied.
Warning: MATLAB did not appear to successfully set the search path. To recover for this session of MATLAB, type "restoredefaultpath;matlabrc". To find out how to avoid this warning the next time you start MATLAB, type "docsearch problem path" after recovering for this session.
Warning: Duplicate directory name: C:\Program Files\MATLAB\R2015a\toolbox\local

This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible.  Error detected was:

Running "restoredefaultpath;matlabrc" does restore some matlab functionality, but there is also a toolbox which I need to use for my work which cannot be accessed in this case. This problem does not manifest itself in administrator mode, but as an intern I cannot be given permanent administrator status simply to fix a glitch with matlab. None of the other non-admin users have this issue, and they have the same permissions as I do. Does anyone have a solution to this issue?

Thank you

Jacob
