What should I do to fix this debug-not-working issue?

Hello,

I am using a R2015a(8.5.0.197613) 64-bit on Windows 7. When I try to debug, the hole debugging menu turns unclickable. Cannot quit, proceed, step in, or else. In order to get out of that status I have to modify the code and save it, or turn MATLAB off and on.

I am not sure if this might be the cause, but it always gives these long warnings and errors when I turn on the software:

"

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

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

I just type "restoredefaultpath" to get rid of the trouble.

What should I do to fix this debug-not-working issue?

Thanks.

You will probably need to use Run as Administrator once, then restoredefaultpath then savepath
