Greetings adventurer,

I'm sorry to hear that this issue persists even throughout all of the troubleshooting you've attempted. After having a look at your system report, I noticed that FINAL FANTASY XIV is currently installed in your [D:] drive. Usually, we would recommend having the game installed on your primary drive, as having it elsewhere can cause certain issues to occur. If you are able to, I would give this a try, but if not, it might also help to try installing it on any of the other available drives that you have as well.

I hope this helps! Thank you for posting in the FINAL FANTASY XIV Technical Support Forums.
