Having previsouly installed and then configured MySQL, you may now need to install the ODBC Data Connector driver in order to connect to your MySQL database.
Following the Splash screen the first thing to choose is the Setup Type for your installation. As usual I chose custom so that I could see the components that were actually being installed.
In this case the custom set up screen allows you to choose to install the driver and the documentation.
Finally you can complete the installation
Assuming it completes okay you have now installed the MySQL ODBC driver.
My intention for installing all these MySQL components is so that I can now attempt to get BizTalk 2009 talking to the MySQL database for a solution that I am currently working on. For this I will next be looking at the Community ODBC Adapter.
