Error when trying to download a new patch

When there is a new patch, this message will always pop out.

After clicking "Yes", it hits an error. So far the workaround is to use Official FFXIV launcher to download the new patch.

Try checking your antivirus

I have disabled all antivirus (Malwarebytes and Windows 10 Anti-Virus) and is still facing the same error.

Hi all, I manage to fix it by changing the "Patch Download Directory". The reason why it was wrong was because I recently reinstalled Windows 10 and the path has been changed.
