Debido a que la versión de Rave Reports para Delphi no incluye los fuentes, la única manera de tener los diálogos en español es crear uno mismo los forms, y utilizar los eventos OverridePreview, OverrideSetup y OverrideStatus del control RvSystem para sustituir los diálogos estándar.

He traducido unos diálogos iguales a los originales (faltaría mejorarlos, por que la verdad es que los diálogos estandar dan algo de pena ) y los he comprimido en este ARCHIVO ZIP. Simplemente hay que añadirlos al proyecto, y añadirlo al USES del form que contenga el control RvSystem.

Hay que recordar que se debe traducir algunas propiedades del control RvSystem para que todo quede completamente en español:

RvSystem.SystemFiler.StatusFormat cambiar a "Generando página %p"
RvSystem.SystemPrinter.StatusFormat cambiar a "Imprimiendo página %p"
RvSystem.SystemPrinter.Title cambiar a "Informe" (Título del informe)
RvSystem.TitlePreview cambiar a "Vista previa de informe"
RvSystem.TitleSetup cambiar a "Configuración de informe"
RvSystem.TitleStatus cambiar a "Estado del informe"

Y por último, los eventos (Probados en BDS 2006):
