unable to open and excute matlab functions

I'm using Matlab 2013a on server 2008 r2, but I get this error code on startup: C:\Program Files\MATLAB\R2013a\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\R2013a\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. Error detected was: MATLAB:UndefinedFunction Undefined function 'usejava' for input arguments of type 'char'. > In matlabrc at 110 Warning: Failed to add default profiler filters. > In matlabrc at 149 Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.mlwidgets.graphics.ModelStateFactory.createNoSelectionModelState(ModelStateFactory.java:242) at com.mathworks.mlwidgets.graphics.PlotToolSetFactory$3.parseComplete(PlotToolSetFactory.java:127) at com.mathworks.mlwidgets.graphics.ModelStateFactory$ProductInfoListener$1$1.run(ModelStateFactory.java:1023) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

Then, I'm unable to open my owm function and it says: Undefined function 'uiopen' for input arguments of type 'char'.

Some users also have this error while the other behave normally. I have tried uninstall and re-install matlab, the problem remains.

Have you tried starting up MATLAB running as administrator?

Ok, problem sovled. I add modification permission of file pathdef.m to all users. Although it may seem unsafe, but at least it works.
