Original Game stopped working after installing BETA

  1. Steam Library right click on Age of Empires IV and select properties
  2. Select “Betas” in the left sidebar
  3. Change option for, “Select the betas you would like to opt into” and set to “none”
  4. Steam will say the game is downloading - wait for this to complete
  5. Launch game.

IF THE GAME SHUTS DOWN IMMEDIATELY ONCE OPENING AND YOU OPENED THE MAP EDITOR BEFORE. FOLLOW BELOW

  1. Navigate to C:\Users\[ your user folder]\Documents\My Games\Age of Empires IV
  2. Open file warnings.log with Notepad or any text editor
  3. Scroll to the bottom of the file or search for the word Failed in a text editor or Notepad. Here will identify what went wrong.
  4. In my case (yours might be different) it was trying to load my test map when I was experimenting with the map editor. You can see in the path below it’s trying to call Test_Map_2.sga.

  1. For my issue, I navigated to C:\Users\[redacted for privacy]\Documents\My Games\Age of Empires IV\mods\extension\local. This path will be different for you if you received an error similar to mine
  2. Deleted my Test Map 2 folder from the path in step 10. This folder will be named whatever you named your test map if you opened Map Editor at any point and compiled.
  3. Launch game and it will work

Issue is that for some reason the map editor when you run a build of a map, it sets a path in the current version of the game and not the test version. Because the current version of the game doesn’t support mods yet, it will fail, causing the game to quit.
