I know this is an ancient post, but it's one of the first results in google for this issue.

This worked perfectly for me, and it completely bypasses the forever-and-a-half patching you need to do.

Just to make the steps look shorter, you just need to enter your Square Enix folder and rename the ARR folder with Backup (or anything that makes it different) at the end; uninstall it, which will take no time, install to the same directory, also taking no time. Rename that new folder in a similar way to the original, and then restore the original name to the original folder. You should then be safe to delete the new folder. Voila, the issue should be gone.
