If you are planning to use Sencha Architect under the terms of our Commercial License, you need to have already purchased a Sencha Ext JS Commercial Software License, or purchase a new Sencha Ext JS Commercial Software License. If you do not own a Sencha Ext JS license but purchase a Sencha Architect license, your development work product will be governed by the terms of the GPLv3 license.

You should have received the activation code in the email you provided when you purchased Sencha Complete. If not (or if you lost it), please write an email to firstname.lastname@example.org to obtain the code.
