After some research, I come to the conclusion that you can download the application only after you reach the support team of their website. They're selling some kind of devices and the downloads to operate them are protected or available only to customers.
Reach their website and get in touch with them saying that you need the software above to finish your work. Keep in mind that they might verify your purchase before providing additional help.
You can find the contact info on their page in the footer area.
