Launcher Error "Unable to complete version update [30426][19900][2]"

[aSnowyEvening]

Made an account specifically to share the solution. On Windows at least, there is an .exe file that deals with DirectX that, for some reason, goes missing.

Program Files (x86) > SquareEnix, Final Fantasy XIV - A Realm Reborn > game
Filename: ffxiv_dx11.exe

If you're missing this, you'll have to re-download the file. This would be why a fresh install of the game corrects the problem.

As for why the file went missing in the first place, I'm still trying to figure that out. Your antivirus software might be at play.

Details are in this Reddit post, including a link to the exe file.

That sounds very logical, I've downloaded the file and will try restoring it if the error shows up again. Thanks so much for the solution, it puts my mind at ease to have a fix!

Had the same issue again this morning. I was unable to apply the fix stated above, when trying to add the downloaded file back to the correct folder, it gave me an error message saying I lacked permission to move files to that folder (strange as I am an admin on my computer. You were correct about the antivirus removing the file however, I use Avast and when I checked the virus chest I found the missing file and was able to restore it to the folder from there.

I have been having issues launching the game for a week or two at this point. I have uninstalled and re-installed the game a few times. I got it to work for a while using DirectX 9 but that is no longer working. Now it won't launch the game at all and says "Unable to complete version update."
When I use DirectX 11, it launches, but when I press start it says "A version update is required. Select OK and launch the game again. 1012"

I can confirm that this solved it for me, at least for now. Thank you very much!
However, I chose to fix the problem within the quarantine of my Antivirus program, where the DX11 file was apparantly stored in the virus vault. Restoring it there and making an exception will probably keep it safe from happening again.

Hello everyone! Adding my voice to this. Apparently the suggested fixes don't work. Tomorrow I'll be reinstalling the game, but hope there will be a reliable solution asap.

Hi everyone. Made an account just to post that I have the same issues with this error code =(. I have also tried all the suggested fixes but so far I cannot play unless I uninstall and reinstall, which I did twice already. Hope I can find a proper fixture for this since I do not wanna reinstall everytime just to play.

TinyRawrs suggested fix worked for me! Found the .exe in the Avast Anti-Virus "Virus Chest." No clue how it got there in the first place but now it works. Thank you! I didn't even know virus chest existed in Avast lol. I am not sure where to direct or how to help others who are using different virus protection but what aSnowyEvening said was true for me - the exe file was deleted by my security.
