This field can only be removed if you have bought the “No Branding” option as explained in the store page:
http://www.htmlexe.com/editions

This option allows you to remove any visual trace that your ebooks and
publications were built with HTML Executable: thus, you can remove the
"Built with HTML Executable" mark displayed in the about box of your
applications and version info. You can then advertise your own company only.

If you want to purchase it, you can contact support by email at http://www.htmlexe.com/contact
