Activate a new software-based license


Call our Ewon by HMS Networks Support Team just to say Hello. You can now activate your new i4scada software-based license by following this tutorial's user-friendly steps.

Following the installation of the software on an end user’s computer the protection and licensing are bound to that specific machine. 


A Software-based-license will be bound to the machine where it is activated.

In case any type of hardware changes are needed, please follow up on the steps described by the Transfer of a software-based license article.

Otherwise, the license will be labeled as a CLONE and will be invalidated. As Ewon by HMS Networks is able to UNCLONE a license for a fee, please contact our Support Team for more details, at
