can not downloading the software to the joystick and microcontroller

I have problem with downloading the software to the joystick and microcontroller. I tried several ways to fix the problem, but I could not. It kept showing me a window saying " Failed to Get Vex system Info (trying to get system info with the cable unplugged).

Could you guide me to the solve the problem ? I tried several ways that I thought would solve the problem, but I could not.

I attached the window photo here

Are you using RobotC? The picture you attached didn’t show up.
