To design the template, we used the Quix page builder. And you don't need to purchase it in order to use the template. It is bundled within the template.
If you are using the quickstart package, you don't need to install it separately. But if you are using the template only, you need to download it from the extension folder (available in the download dashboard) and install it on your website.
PS: You will get a pre-activated premium version only. So there might be some features that will not be accessible.
