A quick and dirty script to install (or uninstall) XIVLauncher locally without flatpak. Assuming you have a native (non-flatpak) install of steam, lutris, or even just wine, the dependencies should be met.

Download XLCSetup.tar.gz from the latest release and extract. Alternately, git clone the repo.

Then run the install script

$ ./xlcsetup --help
usage: xlcsetup [-h] [-l | --custom PATH | -s | -f] [-u | --RB] [--info] [--force] [--tag TAG] [-d] [--clear]

Local install tool for XIVLauncher.Core.

options:
  -h, --help       show this help message and exit
  --info           Show information on the install target without doing anything.
  --force          Force the install even if the current version is up-to-date.
  --tag TAG        Install the latest version as if it were TAG. Useful if the repo version file is out of date.
  -d, --download   Always download the source, even if it's already cached.
  --clear          Clear the cached files and exit.

Install targets:
  Where XIVLauncher will be installed

  -l, --local      Install to ~/.local/share/xivlaucher-core. The default option if no other options are passed.
  --custom PATH    Install locally to a custom location.
  -s, --steam      Install as steam compatibility tool to default path. Steam Deck users should choose this.
  -f, --flatpak    Install as steam compatibility tool for flatpak steam.
  -u, --uninstall  Uninstall the target instead.
  --RB             Install XIVLauncher-RB instead of the official XIVLauncher.Core.

1. Create a new directory at $XDG_DATA_HOME/xivlauncher-local. This is usually ~/.local/share/xivlauncher-local, but if you're running this inside a flatpak, it could be different.
2. Download and extract aria2-static.tar.gz from https://github.com/rankynbass/aria2-static-build. This is a statically built copy of aria2 (built in ubuntu 24.04, but since it's statically linked, that doesn't really matter).
3. Download and extract XIVLauncher.Core.tar.gz from the selected github at https://github.com/goatcorp/XIVLauncher.Core or https://github.com/rankynbass/XIVLauncher.Core
4. Copy over a launcher script and other necessary files.
5. Make a symlink to the launcher at ~/.local/bin/xivlauncher-local. This will allow you to launch from the terminal with a simple xivlauncher-local. You will need to update your $PATH variable to include $HOME/.local/bin, if it isn't already done.
6. Create a .desktop file that points to the launcher, and try to refresh your desktop menu.

1. Download and extract aria2-static and the latest XIVLauncher as above.
2. Copy the necessary files from the resources folder to the steam compatibility tool directory
3. After restarting steam, you can right-click on Final Fantasy XIV, go to settings, Compatibility, and select "XIVLauncher as Compatibility Tool".
4. Now when you launch FFXIV from steam, it will use XIVLauncher.Core instead. This solves the issues with running flatpaks under steam.
5. This is self-updating! It will do a quick version check, and if it detects a newer version it will download and install it. You can test this yourself by going into the ~/.local/share/Steam/compatibilitytools.d/xlcore folder and editing the version file to 1.0.7.0. It will then download again the next time you launch.

You really shouldn't use this, but just in case:

1. Make sure you have permission to the PATH you set. I strongly advise against using sudo to do this; the script can delete files, and you really don't want it to delete anything important.
2. The files will be copied to PATH/xivlauncher-local. A .desktop file will be made in $XDG_DATA_HOME/applications and a symlink of xivlauncher-local will be made in ~/.local/bin.
3. If you want to uninstall it, you need to use ./install -u --custom PATH just like you did for the install. Don't get the path wrong, it can possibly delete files you don't want deleted.
