Need help with launcher :(

Initially game randomly kept crashing 5-15 mins after starting. Nothing would fix it. Decided to uninstall ff14 and try for a fresh install.

Current problem: the launcher will not finish install process. It keeps shutting down and giving “A problem occurred while updating.. please restart [11006][20641][20643]”
For two days I have tried every fix all mighty google and YouTube can suggested to no avail.

What I have tried:
Everything raervis suggested on this post https://forum.square-enix.com/ffxiv/threads/429958

I have tried a vpn, dns server, deleting and doing fresh installs. Removed all overclocking from my pc including ram xmp profile.

Honestly not sure what else to try. Any help is appreciated!

Now it stopped while downloading file: H2017.06.06.0000.0001c at 4.48%.

Error was “unable to download patch files. [30413][10009][10020]”
