It looks to me like this error is occuring because JxBrowser does not have the proper permissions for a file it needs access to in your temporary directory; I have a few ideas that might work.
1) You can try manually changing the permissions for the file (or the directory that contains it) listed in the error message.
2) If that doesn't work or is not possible given your system setup, you can specify an alternative location with the proper permissions as your temporary directory in your java.opts file as explained here:
Specifically, you will need to set the following property:
-Djava.io.tmpdir
You can query the value of your temporary directory using the following command in MATLAB to ensure that the change took place:
>> java.lang.System.getProperty('java.io.tmpdir');
3) As a third option, you can switch to a different version of the default renderer for your help browser by executing the following command in MATLAB:
>> com.mathworks.mlwidgets.html.HtmlComponentFactory.setDefaultType('HTMLPANEL');
4) You can also try changing the renderer altogether with this command:
>> webutils.htmlrenderer(‘basic’);
I hope this helps!
