Errors when using optforce about cobra.tutorials

[tpfau]

You, very likely have Matlabs Text Analytics toolbox installed, which is, unfortunately, shipped with a customized version of the POI library needed for xlwrite. Therefore the POI library that is shipped with the COBRA toolbox is shadowed, and thus can't be used.
Could you try uninstalling the Text Analytics toolbox from Matlab and running optforce again?

Thanks for your help! I find the Text Analytics toolbox. I will try it again after uninstall it.

It looks like you have it installed though. Or some other toolbox that ships with a version of java POI.
What matlab version are you running and what toolboxes do you have installed.
Could you post the results of generateSystemConfigReport() ?
