Cannot load the launcher

When i try to load the launcher it takes a few seconds and then FFXIV Boot Error pops up with the message
Unable to complete version check.
[30605][20448][10009][10019]

I reinsalled the client and have reset my cpu what do i do?

Just gonna bump this

Related, on PS4 I was getting error "E-80552CA7" and it did not load the launcher. Problem went away after a few tries.

Yeah, I'm getting a similar Boot Error which also happened to me yesterday. The error reads: Unable to complete version check [30605][10009]19900][12029].
I have also re-installed the client, restarted my computer and I still get the same error.

Any ideas Square-Enix?

Burlman I've done it a few times over the last few days without any results. My brother just told me a way it might get fixed im about to try it. I will post here if it does.

Great! Keep me posted!

Ok so I just finished what i did so here it is, I do not know if it will work for everyone or what will happen when I turn my antivirus back on but heres hoping its fixed. completely uninstall the game from your control panel, reboot your computer, disable your antivirus and reinstall the game if you are using Microsoft security essentials like I am the way to turn it off (temporarily) is to search for it under the start menu go to Real-time protection and turn off real-time protection (recomended) (this was done on windows 7), I do not know if it will work for everyone or what will happen when I turn my antivirus back on but heres hoping its fixed.

Thanks for keeping me posted! Did this work for you?

Trying to boot game through Steam, launcher fails to verify every time. Reinstalled twice, shut down firewall still no activity.
