168 Bootloader Error

I probably shouldn't be posting here since I obviously have no clue, I guess I'll do it anyway...

You mentioned:

ATmegaBOOT_168_CRUMB168_F20000000_050815.hex

The Crumb168 is a microcontroller module similar to the Arduino Mini

Are you sure this bootloader will work with the Arduino? Do they both use the same bootloader?
