After a fresh install of MATAB 2016a (along side MATLAB 2015b) on a Win7 machine I get the following error message whenever I start MATLAB:
The desktop configuration was not saved successfully
I've seen previous posts about this problem, the suggestion on all of them boils down to checking file permissions for the preferences directory (i.e the directory returned by prefdir) and if that doesn't work then deleting MATLABDesktop.xml and restarting MATLAB.
I've tried both approaches and in fact the above message appears also when MATLAB is run as Administrator. It seems that MATLAB is able to write the MATLABDesktop.xml (it reappears after I delete it and restart MATLAB) but the file contents are always empty.
Possibly related: MATLAB R2016a doesn't save user setting. Similar to that case I have Oracle Java 8 set as MATLAB_JAVA, but I do not get any exception on startup except for the above error. My MATLAB 2015b installation uses the same MATLAB_JAVA but does not fail in saving my preferences.
Any help is appreciated.
