Hi Sam:

The "Adagio" component of Crystal Reports for Adagio won't work with Crystal 11. The only way they can write reports using Crystal 11 is if they purchase the ODBC module. That serves the same function as the "Adagio" component but without the table names and field names in English.

There may be other technical advantages or disadvantages (I've never tried it). But as Andrew said, they definitely would not be able to run the report from the Inquiries menu within an Adagio module nor from PrintTool. PrintTool actually expects that the .rpt file doesn't use any features beyong Crystal 7.
