How to add a message box at the end of the setup?

Hi! How to add a message box at the end of the installation? Thanks!!!


Edit: I use:

[CustomMessages]

english.Finished=The installation is completed.

spanish.Finished=La instalación se ha completado.

and....

procedure DeinitializeSetup();
begin
MsgBox(CustomMessage('Finished'), mbInformation, MB_OK);
UnLoadVCLStyles;
end;

But the message appears too when i press cancel button at start the setup. Any solution?
