Now that we made our C&C:Online account and created our server log in, we are Ready to set up Tacitus

Since you are still logged into the C&C:Online Website, head to the Download[cnc-online.net] page and click the Download Button


Should the Download link not open/be blocked by your browser copy the link and open it in a incognito tab

You now have the file CCO_TacitusInstaller_v1.exe on your system.
We are now going to through the Setup together, so we start with double-clicking the file CCO_TacitusInstaller_v1.exe.


After double-clicking the installer and clicking "next" you will be greeted by this window here


Here you can read the License agreement and accept it or deny it (denying it will not allow you to continue with the installation).
Then you are going to click the button "next"


You are now seeing the installation selection screen where you can specify what games you want to apply Tacitus to.

The games will have to be run at least once before tacitus can actually see them this will be changed in the next update



Now you will see the installer report first this




Tacitus does not have a icon your desktop, your start menu folder or a .exe in your game.
It is directly baked into your game and you can just launch your game from steam and follow the steps on how to connect in this guide.

Now that we have everything set up and working so far, let's get ourselves into the game and into the action.

Assuming that everything until now has worked, and your game is running, and you are seeing the beautiful main menu of Red Alert 3.

Go and click on the big old Multiplayer and then Online Buttons


Once you are in the online window, you are going to log in with the Server Account you created earlier and enter it in the fields.


Important to know is that Your Online ID is a Nickname you can have 16 of those, and they do not have to match your login or display name.
