AutoLaunch is an optional feature. It will run the Archlord executable from the configured path, log on to your Archlord account, and load your desired character from the specified server.
This feature may be especially useful when you configure the fighter bot to automatically exit when your character's HP is too low. As soon as it exits Archlord, the AutoLaunch will start Archlord again, log back in and continue the fight from where it left, but this time your character's HP will have time to be restored during the few first seconds of being invincible after logon.
This feature can also be used to recover from Archlord crashes, or when your game loses server connection and closes unexpectedly. It will automatically kill any resulting Crash Report windows that pop up after a crash in order to prevent accumulating such windows if multiple crashes occur.
Your username and password is encrypted with a powerful standard algorithm (AES-256) and stored in the registry. If you don't wish to use this feature, set it to "No automatic launch". This will also clear the username and password stored with the profile.
