My system does not recognize the familiar(family) license
Can you post the first part of the license key you got (the part before the dash)?
I do not understand(include) your message please explain
You would have been sent a license key by Avast. Igor is asking for you to post the information on the first part of that key, before the hyphen.
(and in Spanish)
Usted ha enviado una clave de licencia por Avast. Igor está pidiendo para que usted pueda publicar la información en la primera parte de esa clave, antes del guión.
Please stop posting the same topic in different threads.
(and in Spanish)
Por favor, deje de publicar el mismo tema en diferentes hilos.
Do not post twice the same…
Is your system time and date correct?
He(She) says that the system allows the access to avast or slightly this way I do not remember. 
Alguien que hable español,
Cuando voy a registrar la licencia dice que esta no es validad, cuando abro el outlook sale diciendo que la aplicacion no puede ser ejecutada, que hago?
I cannot insert by any means l alicensia, there goes out a notice that he(she) says that the license is not cost(been worth), when I open the outlook says that avast cannot be executed :-\
What website did you get your copy of Avast from?
