Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

I do apologize for the delay in response to this issue. The 6d error may occur when background processes interfere with the game's startup.

- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Please be sure that Final Fantasy XIV is installed to the C: Drive.

Additionally, can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display'.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
