Templates supplied with QPR Modeling Client may require a license in order to use them. Models based on licensed templates require a license as well, so models based on a licensed template can be opened only on those QPR ProcessDesigner or QPR EnterpriseArchitect instances which have been licensed to use the template. Once a license has been to a model, it cannot be removed from it. Note that copying or importing elements from a licensed template or model makes the target model require a license, similarly as using a licensed base model.
