Inside the game folder there are two launchers, ACValhalla and ACVallahha Plus. What is the difference between them?
In order to support Ubisoft+ some games will include an additional .exe file. This will come as a patch for games that you already have installed and be included as part of the download package for new installations, however it will only be used to launch games you have through Ubisoft+. If you do not have a Ubisoft+ subscription, you will not use this.
As a heads-up, these forums for Assassin's Creed Valhalla have been discontinued. You can find and post on our new Player Support forums for the game here if needing further assistance in the future.
