FINAL FANTASY XIV Online: FFXIV Boot Error (Workarounds)

How to fix it

1. Reinstall the game

   • Uninstall FFXIV completely.
   • Download a fresh installer from the official source and install it again.
   • After reinstall, launch the game normally.

2. Run the boot executable directly

   • Navigate to the game’s installation folder.
   • Double‑click ffxivboot64.exe to start the client.
   • This bypasses the launcher and can sometimes avoid the version‑check error.

3. Create and use a different Windows user account

   • Log out of your current Windows profile.
   • Create a new local user (or use an existing one) and log in.
   • Install or copy the game files to this account and try launching from there.

4. Switch to a public DNS server (e.g., 8.8.8.8)

   • Open your network adapter settings.
   • Set the IPv4 DNS servers to 8.8.8.8 (Google DNS) and 8.8.4.4 as secondary.
   • Save the changes, restart the PC, and try launching the game again.

5. Power‑cycle your network equipment

   • Turn off both the PC and your router/modem.
   • Wait about 30 seconds, then power the router back on, followed by the PC.
   • Attempt to start the game after the network is fully back online.

If it still doesn't work

• Test the game on a completely different internet connection (e.g., mobile hotspot).
• Check for any firewall or antivirus software that might be blocking the version‑check request and temporarily disable them.
• Contact Square Enix support with the exact error code [30605][505] and details of the steps you’ve already tried.
• Consider posting the issue on the official Steam forum thread for FFXIV, as other players may have discovered additional workarounds.
