Without proper system information and an actual explanation what the problem is, nobody can tell you much.
The translation may not be working well. Are you saying you can't install version 13? It is not an update to version 12. It is a brand new version that installs alongside version 12.
E porque tento instalar um versão mais atualizada do que a minha que e a 11.0 entende ai não atualiza!
The latest update for version 11 is 11.0.4
Versions 12 and 13 are not updates to version 11. They are completely different installs. If you are subscribed to Adobe Creative Cloud, you can install After Effects CC which is version 12 and you can install After Effects CC 2014 which is version 13.
