I just noticed that there are 3 different webpages where you can download the installer. As I mentioned above, it would be appropriate for the developers to add a note, maybe near the “Download” button, on the webpage (or the webpages) where the dynamically tracked installer is downloadable.
Moreover in the second link they should correct the webpage / link title as the firewall is included only in Premium version which is subscription-based, not free of charge. Pasting that webpage URL here has shown that wrong info.
