Installing and running HorizonXI on Linux

The following is for installing HorizonXI, a FFXI private server on Linux. Specifically, I am installing with the following Arch Linux System:

touma@setsuna:wine/x86_64-windows $ neofetch
                   -`                    touma@setsuna

Install HorizonXI - wine-staging (non steam-deck; steam deck below)

Prepare a version of Wine with the proper patches

**tldr; install wine-staging if you want something simple (such as yay wine-staging) and you’re good to go.

You need a version of WINE that won’t crash when accepting the EULA, presumably like most XI installs. There are a couple options here.

  1. “Easy, recommended”: Use a variant of WINE that has the patch integrated into it already, such as wine-staging (here). If you are on Arch Linux, you can do this using pacman -S wine-staging (or any other helper you use). You can find wine-staging in some other repos as well, such as the Ubuntu ones. You can find more on the WINE install page. There are other versions that include that patch in their definition – any of them will do.
  2. “Easy, works in a pinch”: You can download a patched imm32.dll from the web such as https://github.com/bluffnix/ffxi-wine/tree/master/linux and replace your system library with it. You can find some directions on the web to do this – I would recommend you don’t do this because every time you update the operating system and the wine package it’s going to get replaced with a new binary. However, I wanted to write this here since it’s shown on the web a lot as a drag and drop solution from a lot of users.
  3. “Hard”: You can compile a version of WINE that has the proper fix. The patch in question is this. If you are an advanced user, you can do this if you can’t replace your system wine. If you do this, make sure you compile WINE with 64 bit support since you will need it. If you need help with this, leave a comment but for most users this shouldn’t be needed and should only be done if you can’t use the other options.

At the time of writing, this worked with:

touma@setsuna:tidus $ wine --version
wine-7.22 (Staging)

Note: A lot of places on the Internet tell you to use a specific prefix architecture for Final Fantasy XI; this does not work for many private servers – so please follow the directions very closely. If in doubt, follow step by step and start with a fresh prefix.

Prepare a new prefix for HorizonXI using the following command:

WINEPREFIX=~/.wine-horizonxi-64 winecfg

Check that “Windows 7” is selected as the version.

Moving along, let’s run the installer inside of WINE:

WINEPREFIX=~/.wine-horizonxi-64 wine "~/Downloads/HorizonXI-Launcher-1.0.1.Setup.exe"


From this point, you can click “Install HorizonXI” and things will begin working:

  1. An install directory, you can leave that as a default but it defaults to your virtual “Users” drive. I left it there since there is no harm (virtualized drive).
  2. You do not need to login to install the game from what I can tell.

That’s it as far as we know right now.

Install HorizonXI - Linux Desktop using Lutris (non steam-deck; steam deck below)

Lutris is meant to be an all-in-one installer, however there are additional steps required at present to make it work. If you want a quick solution that will work use the process listed above. Otherwise follow the instructions below. Once new Lutris runners are shipped with Lutris i’ll update the script and this guide. Should be early next year for a new runner.


You need to have wine-staging installed.


  1. Open Lutris and hit the (+)plus in the top left.
  2. Select install from YAML file, select the Horizon-XI.yaml file, and follow the steps in the installer.
  3. Once completed hit Close not Launch(it will open but crash if you launch).
  4. Right click on HorizonXI in Lutris and select configure, go to runners and change it to wine-staging 7.22, then save and exit.
  5. All done open HorizonXI you will get a launch prompt asking for either HorizonXI or the 4GB Patch. Select HorizonXI and install like normal.

Note: You might get an error about missing the prereqs.zip, this can be ignored as lutris installed all pre-reqs automatically for you. If you experience the “black void” while changing areas you can lower your textures some in the HorizonXI Launcher. You can also use the 4GB patch i’ve included.

4GB Patch

Windower 4

If you want to install Windower follow the README.md provided in the archive you downloaded earlier. Unless otherwise requested by Vaughan I won’t clog this guide up with that install process.

Guide by: Ex1L3 in the HorizonXI discord, feel free to ask question etc.

Install HorizonXI - Steam Play (Steam Deck / other systems)

There is an video that goes with this guide if you would prefer: https://www.youtube.com/watch?v=4pWbxU025Ak

If you are new to Proton or Linux, it may be valuable.

The following is for Steam Deck users:

Automatic installation

Download Trent’s script and execute in konsole.

Follow the prompts instructions, and report any bugs in the Steam Deck Thread tagging @trent with a snippet including the konsole logs.

For those who click through without reading the basic idea is to install the base game with v1.0.1, then when that is fully completed rerun update-horizon.sh and it will update the installer for you to the latest.

Manual installation

  1. Boot your Steam Deck into “Desktop Mode”
  2. Install ProtonQT from Discover (link)
  3. Open up “Firefox” and “Steam”
  4. Download the installer from the website. It will end up in ~/Downloads
  5. Open a terminal and do the following:

Note: At the time of writing, the installer from the website may not work due to some breaking changes. You may need to install from https://github.com/HorizonFFXI/HorizonXI-Launcher-Binaries/releases/tag/v1.0.1 first, and then upgrade later. The install process seems broken on Linux on the newer launcher

mkdir ~/horizon-xi
cp "/home/deck/Downloads/HorizonXI-Launcher-1.0.1.Setup.exe" ~/horizon-xi/installer.exe
cd ~/horizon-xi
7z x installer.exe
7z x HorizonXI_Launcher-1.0.1-full.nupkg

OK, that’s done.


  1. Launch ProtonQT-Up
  2. Install “GE-Proton7-42”
  3. Restart Steam / deck if you can’t restart Steam from desktop

It should look something like this:



  1. Now, open “Steam” and add a ‘Non-Steam Game’ and navigate to ~/horizon-xi/lib/net45/HorizonXI-Launcher.exe for the executable (you may have to change “.desktop” at the bottom to all application types)
  2. Right click the new entry, hit Properties > Compatibility
  3. Change to the new version of Proton GE you just installed

Launch the game!


Begin installing. You should pick C:\Program Files when prompted for an install path. You should not pick anything else. You can move compatdata to an SD card later if needed.

The launcher has some bugs. Continue down to FAQ down below to find any problems you might have. You may want to read them all before clicking install.

When install is complete you can run:

sudo find /home -name "HorizonXI.zip" -type f | sed 's/ /\\ /g' | xargs -i rm {}

… to clean up the ZIP to get some space back. You may want to save a copy if you want to install somewhere else in the future.


The gamepad needs configuring to work. In game mode:

  1. Open the launcher open the Gamepad Configuration
  2. Enable XInput

In desktop mode:

  1. Open Dolphin to /home/deck/.local/share/Steam/steamapps/compatdata/<prefix_id>/drive_c/users/<user>/AppData/Roaming/HorizonXI-Launcher/ (protontricks can help find the ID)
  2. Open config.json
  3. Make the following edits to the config:
"padmode000": {
    "name": "Gamepad Settings Controls",
    "key": "padmode000",
    "value": [


"padsin000": {
    "name": "Button Mappings",
    "key": "padsin000",
    "value": [

Gamepad should now work in game mode. Credit goes to Sabriel@ for the gamepad directions.

FAQ for Linux

The launcher keeps crashing while trying to install the game

… and it’s wiping all my progress!

Mandatory warning from the HorizonXI staff:

Please note: We will not offer support for users that bypass the launcher with this setup, it’s a work around for users having memory issues due to having less than 16gb ram on PC.**

Still with me? OK, next.

There is a memory leak in the launcher as of launch day. The launcher does not save progress. The staff are working on fixing it but in the meantime, you can follow the below steps to get it working:

  1. Launch the installation once
  2. Let it begin downloading some of the files
  3. Kill the launcher
  4. Grab the magnet with your favourite torrent client – you can use a PC for this and transfer the file to the deck or just install something like Transmission / Deluge / qtBitTorrent on your Deck to use.
  5. Wait for the download to finish. It won’t crash :)
  6. Open Dolphin (file manager) and navigate to /home/deck/.local/share/Steam/steamapps/compatdata/2237253119/pfx/drive_c/Program Files/HorizonXI/Downloads/.
  7. The above path is an example – your randomly generated number after compatdata is probably different and the install path depends on what you picked.
  8. Place the ZIP in this folder
  9. Open Dolphin (file manager) and navigate to /home/deck/.local/share/Steam/steamapps/compatdata/2237253119/users/<user>/AppData/Roaming/HorizonXI-Launcher/config.json
  10. Open config.json and modify the file:
		"baseGame": {
			"downloaded": false,

should be replaced with:

		"baseGame": {
			"downloaded": true,

If you open the launcher, it should now finish installing the game.

Launching gamepad configuration prevents my game from launching anymore

Sorry about that. It looks like a bug. Windows users are reporting the same.

You have two choices:

  1. Re-install and don’t click Gamepad configuration – the bug should be sorted “soon”
  2. If you need gamepad support (Deck / using gamepad out of the box), you can follow this guide: https://www.youtube.com/watch?v=0UYdFoaVnOE&lc=UgywlUbnFvFWxBUOzW54AaABAg. It’s not supported by the team, but has been confirmed to work on the deck.

A patch is supposed to come soon for gamepad players.

I can’t see buttons on the UI

The launcher has a fixed size. You can open the Steam keyboard and use tab to move around controls you can’t see, dock your Steam Deck to a montior / TV for more space, or use KDE window management features to move it around (google: “kde move window with mouse”).

The launcher is showing all black

DXVK can cause this on some older cards. Disable it.

I’m getting told I can’t run it as admin


You’re probably trying to run the installer as-is from the website. Don’t do that; follow the directions above closely and make sure the item you added in Steam is the extracted HorizonLauncher and not the setup.

4GB Patch

Allows the game to use 4gb of RAM instead of the default 2gb. The disclamer in the discord says VRAM but Thorny(the Aurthor of the patch) says it increases RAM allowance of the executable.

  1. If you are using the Lutris install script then:

    Launch HorizonXI in Lutris seclect 4GB Patch option and hit ok.

    If using the base wine install then:
    > Download the Patch here and extract the archive.
    > Run the patcher inside your prefix

    WINEPREFIX=~/.wine-horizonxi-64 wine "~/Downloads/LargeAddressAwarePatcher/LargeAddressAwarePatcher.exe"

  2. Navigate to C:\PATH\TO\HorizonXI\bootloader\horizon-loader.exe
  3. Hit Patch, OK, and close the Patcher.

Where can I get artwork for my install?

You can find some at assets.

These are offical art assets cut for the Deck. Thanks to trent@ and Aku@.
