1. Fill in your details
Fill in your registration details in the dialog that says Activate Zesture Trial and click the Activate Trial button.
(It is very important that you fill in your genuine details since you will receive your Zesture license key in the email that you specify here.)
2. Start the App
When you see a message like "Congrats, your free trial has been successfully activated. You can now start using the app.", click the Start the App button to start Zesture.
