To make Combined Operations:

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.

Or Delete the 2 shortcuts, copy Addons and the Dtr folders from Arma 2 and paste them into the Operations Arrowhead directory.
This helps if you come across errors like.
deleted.chernarus, caweapons_ammoboxes, CAWater, cawater2_fishing_boat
No entry bin/config.bin/CFGVehicles/Land_Fire_barrel.scope
DayZ Mod + Other mods
.:: DayZ Mod Install ::.

DayZ Mod - Download latest from
Install extract and install into Operations Arrowhead Directory with the name of @DayZ

Create a shortcut:

Right click desktop or folder location of your choice.
Replace "yourlocation" with your game location =)

Start In:C:\yourlocation\Arma 2 Operation Arrowhead
Target:"C:\yourlocation\Arma 2 Operation Arrowhead\Expansion\beta\arma2oa.exe" "-mod=Expansion\beta;Expansion\beta\Expansion;@DayZ;" "-name=TOG | Fully" -nosplash -emptyworld

A break down of the above target line.
First part in the "" is to the executable location.
Second part in the "" is were the mods are located that you want to launch.
The mods that we want to launch to run DayZ are, Expansion, beta and DayZ mods, with the correct location from the Operation Arrowhead root directory.
Third part in the "" is the profile I want to start the game/mods with.
-nosplash = No game intro movie.
-emptyworld - Empty World, Just sky and sea :P

Other useful information.
Say you want to play Day lingor, Just change the @DayZ in the target line to @DayZ_Lingor. If you want to play with more than one mod just separate with ; after each mod.

Six Updater
.:: Six Updater ::.

Download and install Six Updater. new=true

When SIX Updater has finished installing, have Launch the program ticked and click on Finish.
Six Launcher will now open. We don't want to use this, so close it.

It will then update itself to the latest mini-version. Just let it do this and accept any UAC prompts that it gives.

When you are prompted whether you want to enable SIX Updater's multiplayer features, click on No.

Now go to your desktop, and launch the program called SIX Updater (not Six Launcher!).

When it launches, SIX Updater will ask you whether you want to run a ping test to its mirrors. Click Yes to this.

Now that you are in SIX Updater, you need to change a few settings. Click on the ribbon at the top left, then click on Options:

On the options screen, ensure that AutoConvert, AutoProcessModApps, and AutoStartApps are ticked, and that Multiplayer is NOT ticked.

I also recommend that you choose to run the game with High priority.

Now click on Ok and wait for it to save your settings.

When it goes back to the main screen, go up to the top center of the screen and set your Profile to ;A2 OA Combined Ops (Forced.


Step 2: Install The Mods (Using SIX Updater)

Now we will install the DayZ mod(s) using SIX Updater.

They are quite large, so this can take some time.
To install them we need to make a SIX Updater preset. A preset is a collection of mods which when you choose to, SIX Updater can perform actions to (eg Installing or Launching) together.

So the first thing you will do is right click on the whitespace on the left of SIX Updater and click New Preset (Right Click), to create your first preset.

Then right click this preset and click "Rename Preset, and call it Mods. The name doesn't matter much, but that is what I will be referring to it as throughout this guide and in any tech support on the forums here.
Now you need to enable the Arma 2: CO beta patch in SIX Updater. This will provide the latest updates and bugfixes, and will not interfere with your base game in any way.


To do this, you are going to click the Beta tickbox at the top of SIX Updater twice so that it becomes a tick (NOT a square!).

You should then see expansion/beta in your Mods preset. The r number after it does not matter. For me it is green, but for you it will be blue.

Now click on and look at the Mods tab (not preset, but tab) in the middle of SIX Updater. This lists all the mods that SIX Updater can install for you.

To do this, right click on the mods (one at a time) and click Add to Preset. You will do this for:



Some mods get added automatically because the mods we have added require them. These are called dependencies. In this case these are expansion/beta.


Now, right click on your Mods preset, go to Updater actions, and click on Install or Update Mods.

You will get a lot of licence agreements. Just wait until Accept becomes clickable and click it on all of them. It may be annoying but you'll only have to do it once.

You should now see a progress bar coming across as you did with the beta preset. The mods combined are about 116MB, so depending on your download speed this may take a long time. When it is finished, your preset will be green, and all the bars will read 100%.



Step 3: Create the DayZ Launching Shortcut.

Now we are going to create the shortcut that you will use to launch the game with DayZ running.

Before you make the preset itself, you need to set the shortcut parameters in SIX Updater.


In SIX Updater, click on the Game Profile tab.
Set the Player Profile to the name that you use to play multiplayer.

Tick Beta, noSplash, noPause only.
If you are using multiple GPUs through SLI or Crossfire, tick winXP, but if you are not then do not tick anything else, and ENSURE that showScriptErrors is NOT ticked!

Now you can make the shortcut itself. Right click on your Mods preset. Go to "Create Shortcut", then "Create Shortcut with Execute and Shutdown and click Install or Update Mods and Launch the Game.
SIX Updater will now create a shortcut on your desktop, which you will use to launch Arma 2 with DayZ in the future.


Specifically, it will launch any mods that are in your Mods preset. If in the future you add maps or other mods to this preset, your desktop shortcut will launch them too.

You may want to rename it to DayZ to avoid confusion".

That is it =)
Done =)

What you waiting for? Click your new shortcut and start playing.

You should have something that looks like this.


Top left = player menu, with your profile loaded.
Top right = the Mods that are loaded, Expansion, beta and DayZ.

Bottom right - top line = 1.62.xxxx - Beta patch version.
Bottom right - Bottom line = - DayZ Mod version.

Extra - Wasteland MOD!

Add these mods to your new preset - Rename it Wasteland.
(Follow step 2 and 3 from above)


Download loacations for the above mods.

Might need update, 2 and 3




Should see the following once you click your new shortcut =)


Click Multiplayer.


Now click and edit the filter button and add Wasteland to Mission, And change your host =)


A list of server(s) should show up matching your filter settings.


Here is my shortcut for the above mods.

"C:\Steam\steamapps\common\Arma 2 Operation Arrowhead\Expansion\beta\arma2oa.exe" "-mod=Expansion\beta;Expansion\beta\Expansion; @cba;@cba_a2;@cba_oa;@jsrs;@sthud;@stmovement;@Blastcore_Visuals; expansion\beta\expansion" -nosplash -world=empty -high -maxMem=8192 -malloc=tbb4malloc_bi -cpuCount=8 -exThreads=7

This is getting to the limits of characters in the target line.
I would add the above to a .txt file, then rename the the file extension (.txt) to .bat then create a shortcut to this file =)

@Gunneristo, No you dont have to half this shit!
You just do the 2 top ones, or the top one and any one of the other options =)
Six Updater, Steam and DayzCommander are just different options of installing.
