Generalmente, los autores de componentes ofrecen versiones Trial usando una "protección" que consta en testear si Delphi se está ejecutando o no, con este código, podrás craquear y simular la ejecución de Delphi, sólo deberás colocar esta unit en la clausula "Uses".

Código Delphi [-]
function IsDelphiRunning : boolean;
begin
  Result := (FindWindow('TAppBuilder',nil) > 0) and
            (FindWindow('TPropertyInspector',nil) > 0) and
            (FindWindow('TAlignPalette',nil) > 0);
end;
