The Denodo Express license has some limitations compared to a full license. As per the limitations, ITPilot and Aracne are disabled.
I would recommend you to have a look at the [Limitations of the Denodo Express License](https://community.denodo.com/docs/html/browse/6.0/platform/installation/appendix/limitations_of_the_denodo_express_license/limitations_of_the_denodo_express_license) section of Denodo Installation Guide to learn about other limitations as well.
If you would like to get a trial with all features, please contact firstname.lastname@example.org or fill the contact form at [http://www.denodo.com/action/contact-us/](http://www.denodo.com/action/contact-us/)
Hope this helps!!
