Hi i had the same problem this morning : Unable to complete version check [30410][30607][20457][409]

This solved it for me, Thank you :
Go to :
C:\Users\''yourusername''\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn

Open with blocknote :
FFXIV_BOOT.cfg file

You will have these lines or something similar :
<FINAL FANTASY XIV Boot Config File>

<Version>
Version 2
Language 1
Region 2
EulaAgreement 1
StartupCompleted 1
B4EulaAgreement 0
BootVersionCheckMode 0
ConfigReset 0

Modify and save it as follow :
<FINAL FANTASY XIV Boot Config File>

<Version>
Version 2
Language 1
Region 2
EulaAgreement 1
StartupCompleted 1
B4EulaAgreement 1
BootVersionCheckMode 1
ConfigReset 0

Save the file, close any FFXIV application and try again. It should download the patch after you enter your password.

I found the problem, I just did "save" file instead of "save as" so it didn't work, Save as works, now downloading patch, thanks!

I dont have the file people are talking about

[ElysaProudmoore]

so i dont have that file, i uninstalled my game, re-installed, and the launcher updated to the correct version right away no problems. of course this isnt ideal because you have a 2-3hour download ahead of you if you do this, but atleast it works. better than nothing if you have tried all the previous solutions.
