My SSD died last week! 26gig is the size of my arma2oa folder with these supporting mods;
Beta,Expansion,@CBA,@CBA_A2,@CBA_OA,JRSR,@sthud,@s t_movment,@st_bunnyhop,@st_map_autobrightness,@st_ lb_enhance.

After a bit of digging, I got "use search to find how to run Arma 2 CO" results too often.

The information is in too many places!
Many diffident shortcuts were not working either!

This is how I fixed

error message.
There were a few other error messages like "No entry 'bin\config.bin/CFGVehicles/Land_Fire_barrel.scope"

Install Arma 2, patch to 1.05, then patch to 1.11.
Run the game -might have to install battle-eye.

Install Arma 2 Operation Arrowhead.
Install patch 1.60 + 1.62 + lastest beta patch!

In the OA folder there is a batch file called _runA2CO and _runA2CObeta.
What this does it links A2 with OA in the registry, it also adds 2 shortcuts in the OA folder to the addons folder and the Dtr folder in A2.

Still come up with the above error. So I deleted the 2 shortcuts. Copied Addons and the Dtr folder from Arma 2 to the Operations Arrowhead directory.

=) this fixed my error of deleted stuff. I not sure why it dident work, maybe a windows 8 thing?


Install your mods. I found the six updater would not add the 2 updates (update 2, update 3) for the JRSR sound mod. this was getting me kicked from servers.
@jsrs
@jsrs 1.5 = This is a problem, as it was opening both as different mods.
I installed this into a new directory, added update 2 then 3, over writing any files, then moved it to my OA folder as @jsrs.

I use Arma Launcher to load mods and start the game =)
