Every time I launch Arma 3 from launcher in 64 bit mode it crashes with an Access Violation error 0x00000005. However I can play Arma 3 in 32 bit mode but would like to play in 64bit. I have done everything that's been suggested to resolve violation as per the feedback resolution to no avail. Also I submitted a support ticket and they have now referred this to you.
