Unable to complete version check.

[MistakeNot]

Same story when I first started trying to get online.
I unfortunately discovered that issue with win7 after uninstalling the game thinking my files had gotten corrupted. So I couldn't get the game reinstalled either.
I am currently getting past that after doing the update for Transport Layer Security to 1.2

Got me past this issue but gave me an generic error message in Japanese, no error codes or anything. Just saying game failed so I'm in the process of redownloading again as it seems that messed up the first time.

Enabling TLS 1.2 as described in that Microsoft article worked for me.

i did that after they released the post about windows 7 and mac 32-bit system and still have it
and i dont want to edit the registry its not a good idea

[Vautravers]

I have the same issue on Windows7 64-bit

Searching about this problem on a web browser I found some post on Reddit from 4 years ago about a very similar error (that one was error [30410] [30607] [10009] [19900] [12175] while this one is [30410][30607][10009][19900][12030], directing people to a thread in this forums with a fix through tweaking the registry (titled "Unable to complete Version Check" caused by microsoft easy fix 51044 if you want to try it).

I personally prefer to wait for a less "scary" way to fix this than tinker with the registry

[30410][30607][10009][19900][12030]

I had no issues last night before the servers went down.

Tried to log in this morning to get the patch before I head to work and got this error.

Tried reinstalling

I also have the same problem with entering the game error "unable to complete version update [30410][30607][10009][19900][12030]", please help to fix this.

Is it possible to upgrade to Windows 10? It might fix the error. (I know that some people have rather old devices though and I'm also a firm believer of keeping what's still working, but it might be the end for FFXIV on those devices...)

The following two articles helped me fix the problem on windows 7 64Bit

https://docs.microsoft.com/en-us/mem...tls-1-2-client
https://support.microsoft.com/en-us/...8-11268bb10392

You must have Windows update KB3140245 installed.
Then you must edit the registry tree as defined in the documentation

If for some reason you do not want to read or do not understand the documentation details about editing the registry tree.
They made an "Easy Fix" program that will do the edits for you.

Hopefully this helps someone.

There are a majority of technical and personal reasons people have for not switching to Windows 10. A solid one of which is how Microsoft collects your usage of your OS, including the contents of your hard drive that you access, to build an advertising profile that Microsoft then sells as "anonymous information" to advertisers. This is one of the reasons why, unlike previous versions of Windows, the Windows 10 upgrade is free.

@Wushu if that is the case for Windows 10 what about Windows 11
but i doubt the support is suddenly gone for w7 users as the days before the new patch i had no issues to log in

That has existed for all versions of Windows from 10 onward (including 11). They introduced it in Windows 8 in an update.
