Barcode EAN 13 in Crystal Report

Hi

I need to print out a Barcode EAN 13 from Crystal Report. In Crystal Report there is a functionality called "Change to barcode" but in there I do not have barcode EAN 13. Can anybody help me with how to get this functionality in Crystal. I problably need some kind of plug-in, but where do I get this?

I appreciate any help

Kind regards
