How To: Install ACRE for ArmA 3 (+ download link)
A.C.R.E For ArmA 31: Download and extract the ACRE mod pack (ACRE for A3.zip):
Download2: Place all files (except the plugins folder) in your ArmA 3 root directory (C:\Program FIles\Steam\steamapps\common\Arma 3\). Overwrite any previous files you have,
except the userconfig folder if it already exists (see Step 3).
3. If you already have a "userconfig" folder, copy & paste the "acre" folder from inside our newly extracted userconfig folder and place it inside your existing one. Otherwise, ignore this step.
4. To start your game with ACRE, add the following line to your game's startup parameters (if on Steam, right click on ArmA 3 > Properties > Set launch parameters):
Quote:
=@CBA_A3;@JayArmA3Lib;@ACRE;
Ensure @CBA_A3 is the first mod in your startup line otherwise ACRE will not initialise.
Teamspeak PluginIgnore this step if you already have the ACRE plugin from ArmA 2.
1: Open the "plugins" folder (from our original "ACRE for A3" download) and drag&drop the 32bit/64bit dll (select one that matches your installation) to:
Quote:
32bit: C:\Program Files (x86)\Teamspeak 3 Client\plugins\
64bit: C:\Program Files\Teamspeak 3 Client\plugins\
2: Launch Teamspeak (restart it if you already have it running) and ensure you run it as
Administrator (right click> Run as Administrator). Within TS go to Settings>Plugins and ensure that "ACRE Plugin" is ticked/enabled.
Still not working?Some have reported that they're ACRE still does not connect to TS, even when they have followed all of the above. A fix that seems to work for most (including myself) is to launch the game using ArmA3Sync (a launcher for ArmA 3). It is perhaps the easiest program you will ever use, yet is still vastly configurable, and loads almost instantly.

Note: If you receive an error whilst installing Arma3Sync, run the installer as administrator.
