Are you using a laptop or a desktop machine? Some laptops do not power the USB ports, or limit the current available from them. In many cases it is not enough to program the chip.
Have you looked at the driver for the USB to serial cable? You need to make sure the buffer is the same size rx and tx, not off by one. Also set it to 115.2kbaud if there is an option.
Are you sure the 9vdc battery is fully charged? A low battery may light the LED but not have enough current to operate the chip.
Are you sure you installed the chip correctly. Pin one on the chip goes closest to the reset button. The two yellow caps are closest to the speaker.
When you apply power to the Bot Board does the speaker make a ticking sound? If so the Atom is installed correctly and the power is sufficient to power up the chip.
The serial port on a PC whether real or virtual will only work with one program at a time. If you have another program open that uses the serial port the editor will not have access to it.

I use a desktop machine

yes i looked for that and i have set the baud rate to 115.2 k.

The battery have exact 9V DC.

Yes the chip is correctly installed

In the driver, there should be a tx/rx buffer. These need to be set to the same value if they are not.
Other people on the forum are stating that they needed to use a powered USB hub to use a Prolific USB to Serial cable, even on a desktop machine. Link.
The fact that the board is ticking is good. This means the Bot Board II and the Atom Pro are at least powered up and working.
Your problem seems to be with the USB to serial cable, or the driver, or another issue concerning serial communication. Have you used the serial port successfully in the past? Do you have access to another machine to try it.
If it works then you can try to find the problem with your computer. If it does not work then it could be a problem with the Bot Board or Atom Pro. Note, 99% of the time it’s not the Bot Board or Atom Pro…
And I ask again. Have you used the USB to serial cable successfully before?
One last thing. The timing for programming an atom is strict. It requires a fast serial connection. This is why we only recommend the FTDI cable. It has an option in the driver called latency. You set it to minimum and it is as fast as a true serial port.
The computer will only allow access to the serial port for one program at a time. Make sure you do not have LynxTerm or some other serial port program running when you open Studio.
