Errors stacked on errors

Greetings fellow Eorzean,

If you are unable to update the Final Fantasy XIV game client due to errors, you may be having transmission or connection issues or permission issues with the client itself. Please try these troubleshooting steps to see if they resolve the issue:

■ Restart communication equipment
Power off your communication equipment for 30 minutes to an hour. Unnecessary data accumulated on the equipment will be initialized, possibly allowing for smoother transmission.

■ Update firmware of communication equipment
Update your firmware, the program running your communication equipment. If the firmware is outdated, your communication equipment may not function properly, so please update your firmware before trying the version update again.

*Consult with the help manual of your hardware when updating firmware. Also, even if your firmware is up to date, rewriting the update may improve the situation.

■ Check settings for security programs and firewalls
There is a possibility that security programs and firewalls are interfering with files related to the game. Please disable these programs before attempting to run FINAL FANTASY XIV. As a last resort, please try uninstalling them for testing purposes.

■ Check security services of your Internet provider
Depending on your Internet provider or service plan, there may be security services included. Please confirm that these security services permit online gaming. If they do not, or if you are unsure, contact your ISP for further details.

■ Close any running applications
Because other applications may interfere with your update, close all other running apps before running the installation file. You can perform a clean boot to ensure no other background programs are interfering with the installation by doing the following:

- Open the Task Manager and select the 'Start Up' Tab. Disable everything here and restart the PC.

■ Remove routers
In order to further diagnose the issue, remove routers and hubs temporarily and connect directly to your modem.

*This may change your connection to a broadband connection. Please consult with your provider for connection settings.

■ Check router settings
Check the settings of security functions (such as SPI) for your router. Also, please forward the ports used for the game. The ports are listed below.

*For details, please consult with the manufacturer of your router.

▼TCP
54992～54994
55006～55007
55021～55040

■ Check your parent folder permissions for the Windows user installing the game
- Make sure the folder/directory for the game's installation and the associated files have full read/write permission.

■ Reinstall FINAL FANTASY XIV
If the installed data or game client updater has been corrupted, the issue may be resolved by re-installing the program.

Make sure to delete the 'Final Fantasy XIV' folder in the 'My Documents' → 'My Games' folder. You can re-download the Windows game client at the following link: http://www.finalfantasyxiv.com/playersdownload/na. Steam users should re-install from their Steam Library.

We hope this information is helpful.
