Quoting it from Reddit:
I have the Steam version of the game, if that's the case for you as well the file location will be different, if you just type ffxivboot.ver in your machine search bar it should pop up pretty quickly. Just right click it and select "Open file location" to make sure you are moving it back to the right folder. Hope this helps!
Just want to say thank you so so much, this worked for me.
