Error loading firmware file apm 2.8 mission planner

Hello, I’m newbie here. I can’t install the firmware by tapping an quad icon, it says “error loading firmware file”. How to fix it?

I’d successfully installed “ArduCopter.hex” file from “theArduCopter_APM_2.0_Firmware_3.2.1.zip” through the “load custom firmware”, is it the same thing? Indicators in “flight data” work fine when apm is connected.
