error [11006][20641][20643] (again)

It's possible that the updater is throwing the patch into an outdated folder, maybe from the beta.

Only thing I can think of in that case is:

1. Check if you have the old FFXIV:ARR Beta still installed, and if so find where it's folder is via properties.
2. Uninstall the BETA version of FFXIV:ARR
3. Check the folder where the BETA was located and look for any trace folders, like "ffxivpatch." If they're there, delete them and see if you can fully download the patch.
Hope this helps.
