I’m seeing that many people have problems with that, here are some steps to follow.
MICROSOFT STORE
Remember that you’ll need to update your game in the Microsoft Store:
- Open the Microsoft Store.
- Click the [ ∙ ∙ ∙ ] symbol next to your profile picture.
- Select Downloads and updates.
- Press the Get updates button to automatically detect, download, and install the latest changes to your game!
- Open the game. The title screen should show you on Build 15.30007.
If you are unable to launch the game after downloading the update, make sure you add (or re-add) the Age of Empires III: Definitive Edition client or folder as an exception to your firewall and antivirus program.
That’s it; you’re ready to play!
STEAM
Remember that you’ll need to update your game in Steam:
- Open Steam.
- Click on Library to see your games list.
- Click Downloads at the bottom of the Library window.
- [If the new build does not download automatically,] click the Download Now button to manually download the new update.
- Open the game. The title screen should show you on Build 15.30007.
That’s it; you’re ready to play!
XBOX APP WINDOWS 11
Remember that you’ll need to update your game in the Xbox App for Windows.
- Open the Xbox app.
- Games that are installed show up on the left side of the app.
- Hover over the game or click it, and then select Update.
- [If the new build does not download automatically,] hover over the game, select More Options (…), choose Manage. Under the Files tab, choose the option to Check for Updates.
- Open the game. The title screen should show you on Build 15.30007.
That’s it; you’re ready to play!
If none of that helps, try this.
If you still don’t update, try uninstalling all of your Mods.
