Require Password to install firmware

So I just started to install the RPC3 PS3 simulator and everything was going fine untill I installed the firmware. The firmware file is password protected while I see vids where people just install it without entering a password... I can't seem to find any sort of password to install it so i'm just confused at this point.

There is no password protection on the firmware file, it's not even a PC native compressed archive type.
