You do not need to have a steam client installed to run the steam version of the game.
  1. Install the client (not steam).
  2. Create a shortcut for ffxivboot.exe
  3. Right click on the shortcut -> properties
  4. In the target field, you should see something like this depending on the location of your square enix folder: "C:\Program Files\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot\ffxivboot.exe"
  5. Just add -issteam so it looks like "C:\Program Files\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot\ffxivboot.exe" -issteam
  6. yes
