Hola a todos,

Sí; utilizando la siguiente función, si bien, probándola, he visto que todo parece ir bien excepto el "FileVersion"... parece que esa "clave" en particular no se cambia y no sé bien porqué ahora mismo... en fin... espero que te pueda servir.

Código Delphi [-]
(*
  Important about this method:

  This method can update the executable version information WHICH IS ALREADY
  SET FROM THE EXECUTABLE'S PROJECT'S OPTIONS!!!!

  What we do is to set a dummy 255 empties characters in every version
  information key, so, we can update it here up to 255 characters that keys.

  This is the only way in which we get this working!!
