Installing Windower

Installing Windower

Windower is available for free at and xiloader.exe is available for free at

Windower provides the connectivity and addon interface and xiloader.exe provides the launcher required to connect to a private server (LandSandBoat is the name of the private servers and the loader is maintained by their developers).

Current Versions

  • Windower: v4.3
  • xiloader.exe: v1.0.5
  1. Download xiloader.exe and place in your \Program Files (x86)\PlayOnline\SquareEnix\PlayOnlineViewer folder. This acts as the “PlayOnline” loader for private servers.
  2. Download the Stable release of Windower and place it in a folder on your computer. It will automatically download the components it needs, so be sure it’s not simply sitting on your desktop. For this guide, we’ll assume you’ve placed it in C:\Windower4.
  3. After installation is complete, open Windower to generate your initial settings.xml file. Once it has launched, click the x in the top right to close Windower for the next step.

Configuring Windower

Unfortunately, Windower is targeted at the Retail servers and requires a bit of extra work to get working for a private server.

  1. Navigate to your Windower installation directory. This is usually at C:\Windower4.
  2. In this directory, you’ll see a settings.xml file, open it up in Notepad (or NotePad2, if you want proper line endings).
  3. For a new installation, your settings.xml will empty. See below for examples of the key values and descriptions.
  4. Save settings.xml and re-launch Windower; you’ll see the new listing. Double-click to begin connecting and the xiloader.exe will appear.
  5. The first time you connect to, you’ll need to press 2 create a new account. If you already have an account, you can press 1 to login and continue (or use the autologin if you’ve added your username and password to the settings.xml).

Xiloader Login


If you find you cannot save the settings.xml file when editing it, try opening Notepad (or your text editor of choice) as an administrator.

uiscale 1.5 optional The base scale of the UI (menus, chat boxes, etc.). At resolutions higher than 1920×1080, 1.5x UI scale is recommended or menus and chat boxes become extremely small.
alwaysenablegamepad false optional If you do not use a gamepad to play FFXI, this prevents the game from constantly querying for it which can lead to lag on some systems. If you do use a gamepad, set this to true.

To configure Windower to automatically log in, update the args to include your credentials.

Example: --server --user YourUserName --pass YourPassword
