Version Check Error

[Ariellendera]

Hello Railgunner2160, Thank you for posting on the Final Fantasy XIV Technical Support Forums.

TLS1.1 and TLS1.2 unfortunately really do not have any baring in this case. I do have some suggestions to help:

Ensure that the latest version of Internet Explorer is installed on your PC (even if you don't use Internet Explorer), please do not use Edge as that is a different internet platform. Once Internet Explorer is up-to-date, please open the IE browser, open the "Tools", go to "Internet Options" and adjust the following settings:
Under the "General" tab, please delete ALL browser history.
Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
Under the "Privacy" tab, please move the slider to the lowest possible settings or to "Allow All Cookies"
Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED.
[SSL 3.0 should be UNCHECKED]
Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
Right-Click on the FFXIV launcher icon and select "Properties"
Go to the "Compatibility" tab, and change the compatibility mode to "Windows 7"
Hit "Apply", then "OK" to save the changes.
Please RESTART your PC now.


Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

Hope to be of assistance.

I've done all that. The problem is most definitively related to the DefaultSecureProtocols registry entry. I tested the launcher both before and after adding the DefaultSecureProtocols registry entry to the registry. The launcher works perfectly before I add the DefaultSecureProtocols registry entry and starts throwing the Version Check error after I add the DefaultSecureProtocols registry entry. The Launcher begins working again After I delete the DefaultSecureProtocols registry entry.

It doesn't matter if the DefaultSecureProtocols registry entry is added manually, or by the "EasyFix" program from Microsoft, once the DefaultSecureProtocols registry entry is removed either by manual deletion or by SystemRestore the launcher works perfectly....
