Unfortunately, it's impossible to download the software. All the websites I have visited had the product listed as commercial which means that you can acquire the setup package after you've paid for it. There is no public download or a way to obtain a demo/trial to register it in case you have the serial number or license key.
I recommend contacting the one you've got the controller from because they might give you a discount if you have the device.
