How I can update Zeos 6.6.0 beta to 6.6.6 stable in Delphi 7 ?

when I try to compile ZComponent.dpk from Delphi 7 Packages I got error

Did you compile all packages in the right order?
Core, ParseSQL, Plain, Dbc,Component,ComponentDesign.
SInvalidUpdateCount is a new message constant, so it may be missing because you didn't compile the core package yet (or the result is invisible to the component package).
