Greetings rezmage,

Thanks for providing us with additional details regarding this error. After having a look into the provided system report, we noticed that you currently have FINAL FANTASY XIV installed on your D: drive. Usually, we would advise reinstalling the game on your primary drive, as having it installed elsewhere can cause certain issues. If you have the available storage, we recommend giving this a try to see if it helps with the error (17) that you are currently experiencing.

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