Sorry, I haven't been able to post on this forum for a long time because of the new forums and my browser didn't really like it :P Well, I don't really know what could be the problem, but it could be with the .cmd file, try downloading and replacing the file with this one http://www.mediafire...tju0d6s5md6y8r6 . If still not working, I suggest you to do a full re-install.

Did I say that you need extra .cmd file? no. I said that if it doesn't work, download the extra file. Sheesh, can people read nowadays? :-/

1. Run STEAM as adminstrator. 2. Run ArmA 2, Quit. Then run ArmA 2: Operation Arrowhead, Quit. After that install the desired beta patch.

But the game is not running as CO. Do this; 1. Run STEAM as adminstrator. 2. Run ArmA 2' date=' Quit. Then run ArmA 2: Operation Arrowhead, Quit. (THIS IS ESSENTIAL) 3. Install DayZ with Worrom's DayZ Updater, which you can download from here. http://worrom.com/files/DayZUpdater16.zip 4. Install latest beta patch, which is 1.60.93825, run it as adminstrator also, better be safe than sorry. 5. Add one of the following parameters as a launch option in STEAM to ArmA 2: Operation Arrowhead. The second parameter is the same but in different form, some reports say that some people have difficulties with the default parameter. -beta=Expansion\beta;ca;Expansion\beta\Expansion -mod=@DayZ;ca OR -beta=Expansion\beta;Expansion\beta\Expansion;CA;@DayZ 6. Download "_runA2CO.cmd" from here http://www.mediafire.com/?tju0d6s5md6y8r6 and put it in the ArmA 2: Operation Arrowhead's game folder in "\common\arma 2 operation arrowhead" and overwrite if asked. DO NOT CHANGE THE PARAMETERS IN "_runA2CO.cmd" FILE! 7. Copy & Paste the Beta "arma2oa.exe" from "\arma 2 operation arrowhead\Expansion\beta" folder to "\arma 2 operation arrowhead\" and overwrite if needed, before pasting. Make a backup of the original "arma2oa.exe" by moving it to other folder or by changing it name to something else, like "arma2oa.bak.exe" Cheers! I really hope this helps [/quote'] i didnt think it woud work, but you must be magic i love you :D I'm glad you got it working, have fun! :D

I downloaded your pre-configured _runA2CO.cmd file, and everytime I reinstall the game ( 3 times so far ) it doesn't switch back to the old _runA2CO.cmd file. Do you have any ideas how I could make this work ? I would really like to play on Steam with the overlay, but it's been 3 times so far, I might as well just play without if it doesn't work. Thanks :) The game doesn't still seem to run as Combined Operations, try to download the official and default _runA2CO.cmd file from here. http://forums.bistudio.com/showthread.php?101214-ARMA-2-CO-(how-to-combine-ARMA-2-into-ARMA-2-OA-and-use-together)&s=1d3fc3549a0d26f84c8b788bd599079d

Yes, but Rocket didn't specify the date, It may be Monday, but which day? next week? ;)

I've reinstalled both of them (as mentioned), twice in fact, and encounter the same problem regardless. Then, I'm afraid I have no idea what is your problem, did you try to run both games first as adminstrator before pressing multiplayer?

Agreed, It keeps puzzling me why on earth would you shoot a unarmed fellow survivor, although I understand the fact that they may become a threat if they manage to find a weapon and start tracking you afterwards. I never have shot an unarmed player, but I always warn them not to come any closer or I will shoot them, not deadly but shoot in the leg so they wouldn't start tracking me. If they wan't to group up I may let them follow me and even give some supplies, like a pistol and some ammo. Once I gave a Lee Enfield with 6 mags of ammo and something to eat and drink, after I turned around he shot me in the back, so I'm bit alerted even near unarmed people, they could be carrying a gun in their backpack too!
