The dll's that are used to export the reports into the file formats you want (pdf, doc, xls, etc) only come with Developer or Advanced. The ones that come in other CR Editions cannot be interfaced with by third party applications like CRD.
Secondly, your CR License states that you must have a Crystal Reports Broadcast License in order to use products like CRD. This license is granted to you for free if you own a copy of CR Advanced.
