### InstructionsEdit

In this example we are going to install DayZ. The guide assumes that you have installed and are running Play withSIX.

1. First select the mod, in our example, DayZ. You can bring up the mod selection by clicking the “No active Mod” block, or if a mod is selected, it will show the currently selected mod logo.
2. Make sure Multiplayer is enabled in the Info block under the Mod block, then click this block to enable the Server Browser.
3. Select the desired server, you can use the advanced server filter to find exactly what you are looking for.
4. The action button now should say either Update, Install or Join. Click this button to initiate the action, in case of install/update, wait until it’s done and then click Join to join the server.

If your mod is already uptodate you can simply double click any server to join it.

If you need to configure any game settings, like startup options, installation paths etc, click on the Game block (saying ARMA 2 currently).

## DayZ Steam manual installation Edit

Install ARMA2 beta patch first and then follow DayZ install instructions below.

1. Make a folder named "@DayZ" in your Arma 2: Operation Arrowhead directory.
2. Inside "@DayZ" folder create another folder named "Addons". It should look like this: C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\@DayZ\Addons
3. Unpack all DayZ Mod files in the "Addons" folder.
4. Start the game as instructed in ARMA2 beta patch

If everything is installed correctly you should see "@dayz" line under "ArmA 2" on the right side of the menu screen. Use the filter to find DayZ servers.

## ArmA2 mixed copy (Retail and Steam) Edit

Make sure you install the latest patch for the retail version from http://www.arma2.com/supply/game-updates Then follow the STEAM/NON-STEAM INSTALLATION guide.

## ArmA2: Free and ArmA2: OA Edit

It is possible but not recommended to use the free version (not the demo) of ARMA2 and combine it with ARMA2: Operation Arrowhead to create ARMA2: Combined Operations Lite and use it to play DayZ. This will mean low resolution textures are used for most of the game world.

Here is a guide how to install DayZ with arma2:free and OA: Kodabar's Guide

If everything is installed correctly you should see "ArmA 2 Free" (or "ArmA 2 Demo"), "ArmA 2 Operation Arrowhead" and "@dayz" on the right side of the menu screen.

## ArmA2 Beta patch Edit

From DayZ version 1.7.1 requires "Arma2 Beta" to be installed

Beta patch is not instantly BattleEye enabled after release. You may have to wait a couple of hours to be able to play with it online. To be sure, check the corresponding thread.

Beta patch is backwards compatible, so you can still play on non-beta servers.

If you have previous beta patches it's suggested to uninstall them before installing a newer version. You can also try deleting beta subdirectory inside ARMA 2 folder manually.

1. Download and install beta patch from http://www.arma2.com/beta-patch.php (Latest patch is in the green field top of page)
2. If you are met with a "Password screen" then choose the top version on page (Not in the green field)
3. Go to the Arma2:OA main directory and right-click on shortcut "Launch Arma2 OA Beta Patch". Add "-mod=@dayz" without quotes to the target line.
4. Run "Launch Arma2 OA Beta Patch" and enjoy playing!

NOTE: Remember to install DayZ MOD before launching the game!

## Startup parameters (optional) Edit

You can find other than default launch options, like windowed mode here: http://community.bistudio.com/wiki/Arma2:_Startup_Parameters

## Common errors Edit

I get 'You cannot play/edit this mission, it is dependent on downloadable content that has been deleted.dayz_code, dayz_weapons, dayz_equip etc.'upon joining any DayZ server

You installed the mod or the shortcut incorrectly. Make sure you add "-mod=@dayz" without quotes in the launch options and DayZ mod files are installed in the proper folder. By default: "C:\Program Files (x86)\Steam\steamapps\common\arma 2 operation arrowhead\@DayZ\Addons"

I am stuck at "Waiting for server response" or "Waiting for character to create" or "Receiving Data"

Servers are simply being overloaded, wait a litte or try another server. If nothing works try below.
If nothing works try reinstalling both Arma2 and OA.
Note: Frequent connections and disconnections on a server compound this problem. Please try to be patient before switching to another server.

I get a constant "Retrying to authenticate" message

Updating Arma2 Client to the latest beta version may resolve this issue. Latest versions are available at http://www.arma2.com/beta-patch.php

I get "You can not play/edit this mission; it is dependent on downloadable content that has been deleted.cherarus" when trying to join any server

Make sure you launch the game as 'Combined Operations' and NOT 'Operation Arrowhead' when launching from STEAM.

Invisible objects, missing textures etc.

Right click ARMA 2 in STEAM - 'Properties' - 'Local Files' - 'Verify integrity of game cache'.
Try changing your ingame video settings.

I get other weird graphic artifacts ingame that block my screen

How do I change my FOV (Field of View)?

There's two different guides available for changing your field of view.

If you're aiming for a more immersive, realistic field of view, try this guide instead: http://forums.bistudio.com/showthread.php?100235-Setting-up-your-FOV

I get 'ARMA2 stopped working' error on launch

Right click ARMA 2 in STEAM - 'Properties' - 'Local Files' - 'Verify integrity of game cache'.

I can't use Direct Chat ingame. Mic is stuttering

Known bug. You can install the latest beta patch for Arma2:OA (see above) or wait for the official fix.
