Ok, so I picked up the Combined Ops set off of steam for $30. This is a really basic question that doesn't directly relate to the DayZ mod setup, but to the install just prior to that. Here is the current situation: (1) I can't run Arma 2 on its own. I get an error message saying "bad key" even though I just bought this off of steam. (2) I can run Arma 2: Operation Arrowhead by itself, just fine. (3) I can't run Arma 2: Combined Operations. I'm assuming that this is b/c Arma 2 has the weird key error issue. I am re-downloading Arma 2 right now. Now, question to clarify is: Does Arma 2: OA have to be installed into the Arma 2 folder, as the retail website suggests?: https://store.bistudio.com/arma2-combined-operations OR does the steam installation already handle everything about the setup correctly so that having Arma 2: OA installed into the Arma 2 folder is no longer necessary? In other words, it should've been the case that I download the CO pack, it self-installs and there should not be any further fiddling around around to get Combined Operations to work other than selecting it from the dialog box of options that pops up when I double click on Arma 2: OA from my games list on Steam? edit: seems like the video guide at least clears up this part. The answer is, steam already handles everything correctly. video link: http://dayzmod.com/forum/showthread.php?tid=408 As for the key issue...bleah...Murphy's Law at work. I hope when the download completes again on Arma 2 that that problem goes away.
