Error Starting Matlab, how do I permanently fix this issue without using "restorede​faultpath;​matlabrc" everytime I open MatLab

Everytime I start up Matlab I get the following message:

"C:\Program Files\MATLAB\R2014a\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\R2014a\toolbox\local Warning: Initializing Handle Graphics failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible. Error detected was: MATLAB:undefinedVarOrClass Undefined variable "graphics" or class "graphics.internal.initializeMATLABRoot". Warning: Initializing Java preferences failed in matlabrc. This indicates a potentially serious problem in your MATLAB setup, which should be resolved as soon as possible.

Recovering the session using "restoredefaultpath;matlabrc" does work, but I cannot figure out how to fix the problem so this message does not pop up every single time I start MatLab.

I have this problem too

Do your have write acess to teh file C:\Program Files\MATLAB\R2014a\toolbox\local\pathdef.m ? The message "Cannot open file: permission denied" seems to tell, that the permissions are missing. Can you obtain write permissions? If not, aks your admin. Afterwards try it again.

Does the pathdef.m file look correct? Any duplicate folders?

Jan: sorry, but that is a poor solution.

Individual users should not need to write shared configuration files. That is the entire point of having separate usernames / multiuser operating systems.
