2.3.3.4. The Custom Install Dialog
If you wish to change the installation path or the specific
components that are installed by the MySQL Installation
Wizard, choose the Custom
installation type.
A tree view on the left side of the custom install dialog
lists all available components. Components that are not
installed have a red X icon; components
that are installed have a gray icon. To change whether a
component is installed, click on that component's icon and
choose a new option from the drop-down list that appears.
You can change the default installation path by clicking the
Change... button to the right of the
displayed installation path.
After choosing your installation components and installation
path, click the Next button to advance
to the confirmation dialog.
