Steam Deck
Use the official guide for the Steam Deck flow, then add the game to Steam as directed. This gives you a cleaner path than trying to adapt a Windows-only setup guide.
Steam Deck and Linux
XIVLauncher Steam Deck and Linux Guide
Steam Deck and Linux players should not use the Windows setup file as their primary path. XIVLauncher has a native Linux route documented by the official project, with setup guidance for Steam Deck and desktop Linux.
Which path should Steam Deck users follow?
The official XIVLauncher FAQ says XIVLauncher has a native Linux version that works on Steam Deck and desktop Linux. Use the official Steam Deck and Linux documentation instead of downloading the Windows installer and guessing through compatibility layers.
Desktop Linux
Desktop Linux users should also start with the official Linux instructions because distribution, launcher, and Wine-related details can differ from Windows.
Setup checklist
- Read the official Steam Deck and Linux guide before downloading anything.
- Confirm your FFXIV license and account situation, especially if you switch between Windows, Steam, and standalone service accounts.
- Follow the Linux-specific install path rather than using XIVLauncher-win-Setup.exe.
- After setup, test game launch before adding many plugins.
- If something breaks after a patch, check official FAQ updates and community notes before reinstalling.
Steam Deck search questions
Queries like ffxiv steam deck launcher, ff14 launcher steam os, and xivlauncher linux usually come from players who need a device-specific path, not a generic download page. That is why this page links to the official Linux guide and keeps Windows installer details separate.
