Sound does not work for me or my friend, may be that the torrent package includes the OLD SFX package.

The difference between a 460 and 405 are enormous.

How does this install on Amazon version?

Your Arma II has to be patched to 1.60, and to do that you need to have your OA install in the same directory as the original Arma II install.

Did you update your Arma to 1.60?

Shit when I installed my game I didn't know OA had to be in the same directory. Can I just drag the OA folder into the original Arma II folder?

I bought Arma II and OA just for this, however I've had my fair share of trouble getting the download to work off Amazon, as have most others. Lots of issues with corrupt files, AFTER the download completes- forcing you to redo the entire thing. (8GB/game).
