You can customize the activation messages that will be displayed to the customer. You can include support/contact information if you would like.
Allow activation using another computer internet connection: If your customers do not have an Internet connection for the machine they need to activate, you can allow them to complete the activation through another computer that does have an Internet connection.
Allow deactivation: Enable this option if you would like to allow customers to transfer their license to another computer or user. Performing a deactivation will disable the software on the current machine, and free up that activation to be used on another machine.
Open a browser to a URL after activating: You can optionally open a URL after the user activates. This can be useful if you want to provide additional information that can easily be updated.
