Well there are 2 bios revisions atm
1: 80.10.37.00.12 (AS02) -> Can be flashed perfectly with the 80.10.37.00.AS04
2. 80.10.3A.00.13 (AS03) (seems to be a newer one) -> Can be flashed perfectly with the 80.10.3A.00.AS05
You can find your bios revision through Asus GPU tweak or Gpu-z, but just do find it through GPU Tweak please.
The Firmware updater seems to be extracting the files first and trying to run but it fails. It's quite easy to find the bios rom files, open the updater and it's going to say it needs to be closed don't press OK and leave it and navigate to the folder: HowTo:

When flashing it will do a check if the board revision match:
