Windows 10 - "Final Fantasy XIV Stopped Working"

I was just one the phone with Square-Enix NA support and they were unable to make any real suggestions about fixing my problem.

I JUST decided to upgrade to Windows 10 today (after delaying more than a month for just this reason) because I have read a lot of good commentary on WIN10 installation and FFXIV compatibility - namely that some people were having issues, but they were mostly solved by driver updates or running as Admin / running with Compatibility Mode.

I am not getting a specific Error Code, it's just a "Program Stopped Working" message and then the launcher shuts down. (To be specific: Launcher opens fine, I type in my SE-ID, my password, and my One Time Password - everything good so far - the green Play button appears, I click, BAM - Stopped Responding.)

Things I have tried so far:
* Disabling Windows Firewall (only)
* Disabling Windows Defender (only)
* Disabling both Windows Firewall and Windows Defender (simultaneously)
* Clean Boot with startup programs disabled (suggested by Square-Enix staff; failed)
* Running as Administrator
* Running with Windows 7 Compatibility
* Running with Windows 8 Compatibility
* Running as Administrator WITH WIN7 compatibility, simultaneous
* Running as Administrator WITH WIN8 compatibility, simultaneous

None of these has worked. Anyone else gotten their XIV working in similar conditions? Really don't want to have to do a WIN7 roll-back or "wait and see" til Square has "Official WIN10 Support" =/ It's been 6 weeks since the full version has been public now...

Sounds like DirectX failing to Init. Have you tried switching the DirectX version through the launcher's config? If it manages to launch after changing that, then you may have a missing/unregistered DLL that needs to be addressed. You may also see some details posted in the Windows event logs (eventvwr.msc) that give a hint of the problem as well.

I will check into this Raist, thank you.
I am currently in the middle of a re-install of FFXIV because I'd hit a wall with seeking solutions. If the re-install doesn't work, this'll be my next step.

This thread can be CLOSED - reinstalling FFXIV on the WIN10 computer fixed game.
