Accepted answer

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.

Same problem here. Solution worked +1. I'll just add to those reading this, the "restoredefaultpath;matlabrc" command might take a minute; keep an eye on the busy/ready signal from MATLAB.

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.
