Unable to complete version update [30426][19900][740] AND Fatal DirectX error

After trying to fix the "fatal DirectX error", I am no longer able to log in and am getting the "Unable to complete version update [30426][19900][740]" error.

I've tried everything below (and reinstalled game twice):

We would be happy to assist with your concern. Please try the following troubleshooting to see if this helps with the connection issues you are experiencing. Open the control panel of the PC and go to ‘Network and Internet’. Once there select ‘Internet Options’.

- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.

- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"
*Make sure your fire wall or antivirus program is not interfering with the game

Next, check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

Lastly, we suggest to power cycle the router by shutting down the Router and leaving the power supply unplugged for 5-10 minutes. 

- Flush DNS: Within the "Command Prompt" of the device, please type the command "ipconfig /flushdns".
- Reset TCP/IP: Also within the Command Prompt, type the command "netsh int ip reset" and then restart the computer.
- Delete the Patch Folder: Navigate to the folder using this path This PC > Docs > My Games> FFXIV ARR > Downloads > FFXIV patch (Use for either the version update error or cannot download patch files error)
Then either rename or remove the folder, the next time FINAL FANTASY XIV is launched, the client will repair the folder.
- Change local DNS: Please try changing the local DNS server to 8.8.8.8 and 8.8.4.4
- Delete local files with corrupted character data, please note this will not delete the associated characters.

Hello, please list your hardware first. You can do it in the FF14 launcher -> settings -> system information. Just copy the informations here into the forums. :)



Cheers

Mhhh, it seems, that it is a laptop. Do other games also crash? If yes, then it is very likely, that the laptop has a serious issue.



Cheers

Nothing else crashes. Everything else works perfectly. :( It's a new gaming laptop too. My brother built it for me so that I could play Dawntrail with good graphics.

OK, Laptops are sometimes difficult. ;)

Try the the following: navigate into the C:\Users\username\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn folder and rename the FFXIV.cfg file to FFXIV_back.cfg or so. And then start the game.



Cheers

Still no luck . :(

I'm not sure if the earlier reply worked as I can't see it, but still no luck. :(

It seems, that this error comes from internet connection problems. Maybe your internet provider blocks something. I read, that VPNs ala Nord-VPN may help in those cases. I would give it a try.


cheers

My brother fixed it! Turned out it was a permissions issue - Steam thought it didn't have the permission to launch the game. Uninstalled the game, then Steam, and then reinstalled Steam and then the game. :D No idea how that happened in the first place. Not sure about whether DirectX issue has been fixed as well. We'll see! Thank you so much for your help!
