This can only happen if the ASL database already exists, such as if ASL is being reinstalled on a system and the ASL data was not completely removed. If this occurs, you will need to manually remove the ASL database. To do that, log into mysql as your administrative user (root for example, but check with your OS vendor if you are not sure).
Drop the database by running this command in mysql:
drop database tortix;
Drop the "tortix" user by running this command in mysql:
drop user tortix;
Then run this command inside mysql:
Then run the ASL installer again.
