Wordpress Demo and MySQL

I have the Wordpress Demo installed on two machines. It works fine on one and the database connection fails on the second. The second machine has MySQL already installed on it and it appears that there is a conflict. Does anyone know if just changing the ports for the Wordpress Demo is enough to resolve the problem?

Yes, you can change MySQL ports both in the WordPress config file and in the portable MySQL MariaDB server generated by ExeOutput for PHP - to do that, edit the my.ini file.
