ANSWER:
To create an Online Profile in Anno 1404: Venice, follow the steps below:
2. If this is your first starting game, you will be prompted to create an Offline Profile.

To confirm the entered username, click on the check mark to continue to the main menu.

Here, you can make changes to your profiles, like changing the crest or player-colour.
Your achievements in the game are also visible here.
By selecting the option Profile management on the right, you can continue with the Online Profile creation.


The Online Profile does not allow special characters. Should your current password contain special characters, we would recommend changing your password, to avoid any errors.
After confirming the login details Anno 1404: Venice will now connect to the Ubisoft servers to validate your username and password. On successful validation you can name your Online Profile and confirm with OK.
The Online Profile will show the chosen name as well as the legacy username e.g. ANNOnymous (Online - ExampleAccount)
The creation of the Online Profile is now completed and it should be shown on the right side of the screen below your Offline Profile.
7. If you want to play an Online match, please use the ESC-key to return to the main menu of Anno 1404: Venice. Here, the Multiplayer - Internet option should now be available.


10. Your Online profile is now active and should allow you to join Online matches.
