Follow the instructions in the installation wizard. There are no setting options within the installation.
After the installation open SSDT (formely known as BIDS), Visual Studio 2010 or Visual Studio 2012. If you want to use Visual Studio 2012, you must have installed additional Microsoft SQL Server Data Tools - Business Intelligence for Visual Studio 2012.
In SSDT create a new SSIS project, and open the SSIS Toolbox. You can find the new component in the common group. With SSIS 2012 and the SSIS Toolbox it's not longer necessary to add the component manually to the Toolbox.
