XFX AMD 6600 - now AOE3:DE crashes

Just replaced my GTX 1070 with a 6600. Getting it working was quite the PITA, I had to uninstall my anti-virus.

Now AOE3:DE crashes on startup.

Any suggestions? I’d hate to send this card back but that’s how it’s looking now.

Are you using a 6600? Have you had problems? And if so how did you fix them?
