I've just put a clean install of 2011b onto a newly rebuilt Win7 machine and had the same problem. The issue appears to be that the pathdef.m file is absent, rather than corrupt or mis-located.
Having performed the "restoredefaultpath;matlabrc" fix mentioned above I then navigated to the C:\Program Files\MATLAB\R2011b\toolbox\local folder and typed "savepath pathdef.m". The system now appears to be working normally.

I found this was because of an user access control problem. The file MATLAB\toobox\local\pathdef.m was not accessible.
I had to go to "Program Files\MATLAB" in explorer, right click, properties, security, permissions, Add, Everyone, Allow full access.
This solved the problem.

The accepted answer did not work for me, but this answer did!
So this did NOT work:
1) >> restoredefaultpath;matlabrc
2) cd C:\Program Files\MATLAB\<version>\toolbox\local\
3) >> savepath pathdef.m (and said ok on the Admin prompt that came up and it did write a pathdef.m file)
I also tried to do the same when running MatLab as administrator, but with no luck.
But this did work:
1) Navigate to C:\Program Files\MATLAB\<version>\toolbox\local\pathdef.m
2) right click > properties > security > Edit > Add > Type "Everyone" > Ok > Select Everyone > tick "Full Controll" > Ok
(Note you may need to create the file first, if missing, using the first 3 step)

Did you do what it tells you to do in the message?
"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."
You basically need to get the path into a decent shape (using restoredefaultpath) and then figure out how it got there and fix it (using the doc reference provided)

Yes I did what's told to do in this message.
It repairs the problem temporarily, but once I start for a second time I have the same problem.
Can I create or download a pathdef.m file?

Search all your m-files (I assume you know how to do that in a variety of ways) for "savepath" and see if it's there. Perhaps you're messing up the path and then saving some bad path.

Hello,
I'm using Mac Catalina OS for running Matlab 2019b and I'm getting the following error-warning message when initiating the session:
Warning: Initializing 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:format:UnknownOption
Invalid format option sh.
> In matlabrc (line 52)

I have tryied "restoredefaultpath;matlabrc" but did not work ... and "savepath" as well but also did not work...
Matlab 2019b works and open session in the correct path folder but the warning - error does not disappear
How could I solve this problem ?
Thanks a lot
