FRDM-KL46Z problems to write and debug it with Kinetis Studio

Hello, I am trying to use a FRDM-KL46Z board with Kinetis Studio.


Following some online help I wrote PE OpenSDA on the board and installed PE drivers into my Win7 PC but Kinetis Studio still don't see the board.

Strange because In Device Management I see an OpenSDA device connected to a COM port.

My goal is to be able to develop on the board using both Kinetis Studio and mbed.

This is my error message:
