Is this a freeware application, requiring no additional license? Please advise.
Yes, the product is listed as being Free, but the problem is that only employees or customers can download it. I have tried to obtain it, and a login form is shown instead to log-in. There is no way to create an account on the website which means you will have to contact the developers.
