DCryptor Transfer Error

Question

I have a Nissan Armada 2021.
I have installed the unit SN: 001A07 679868

The unit programmed to the car correctly. All the lights lights flashed in the way the instructions say.
when I come to the computer and go to DCryptor, after I click send data it says ERROR: transmission failed check usb connection. And then it says Receive Error.
Does it every time not matter what I do.

What can be done?
Car now has a key system failure error.
