How to upgrade firmware properly?

Hello folks,
I have a lite-on 411s and i wish to upgrade the firware for it. I have downloaded the newer firmwares i want to try and unzipped them. I have also downloaded flashfix and unzipped it.

Do i just click onthe firmware version itself and does it do theupgrade? are there a sequence of steps i should take first???

thankyou for your help

Yes. LiteOn firmware upgrades are amongst the simplest/easiest out there.
