This is the old-fashioned way of obtaining the software. You buy Captivate and get a serial number to activate your installation. The serial number is valid for a specific version of Captivate, and for a specific platform (macOS or Windows) only. Once activated, that version of Captivate is permanently available on your computer. With this option, you get all the functionalities of Captivate, and you can start working on your eLearning projects right away! You also get all the patches and bug fixes for the version you bought. All the step-by-step exercises of this book work flawlessly with the Captivate 2019 perpetual license.
You can download and use this version of Captivate free of charge for 30 days. This should be more than enough time for you to go through the exercises of this book. However, once the trial period is over, you will not have access to Captivate unless you convert your trial to a licensed version. This can be a perpetual or a subscription license.
