1. Application not starting

1.1 Dialog "Please start steam first!" appears

• Your Antivirus tool may prevent AML from accessing the Steam API. Especially "Comodo Cloud Antivirus" has been known to cause issues.

The Steamworks documentation gives 3 reasons why this might happen:

• The Steam client isn't running. A running Steam client is required to provide implementations of the various Steamworks interfaces.
• The Steam client couldn't determine the AppID of the game. Make sure you have steam_appid.txt in your game directory.
• Your application is not running under the same user context as the Steam client, including admin privileges.

In other words make sure that:

• Steam is running
• the file steam_appid.txt exists in the AML folder
• neither (or both) of Steam and AML are running with admin privileges

1.2 Dialog "XCOM2 Launcher.exe - System Error" appears

If an error dialog similar to this is showing up, it is most likely caused by a corrupt .NET framework installation.

This can potentially be fixed by following these instructions. It may be required to completely remove the .net framework, restart and then perform a fresh install.
