Hawk: Hey everyone, I wrote a Guide for installing DayZ. I have the GOG version so this is specially tailored to this crowd, but also applies to other Non-Steam versions of the game:
A huge thank you for taking your time to writing a very helpful guide!! +++ :) It will surely be of great help to many people!
I've not yet bought Arma II from GOG (stupid me didn't think of looking for it here.. doh!), so I don't know which version the GOG release patched to.
The reason I'm mentioning it is that it seems like that only installing the "beta patch" onto version 1.59 isn't optimal. While it works, some things are missing, 2 advanced video options for example. (AToC and PPAA)
So... if the GOG version isn't 1.62, I'd recommend you test the "1.59 -> official 1.60 patch -> official 1.62 patch -> beta patch" approach. If it is... well, yet another reason I'll buy the GOG release too.. :D
