Thanks,
entering with the way 1 , by UI → settings->subsription-> insert a license file → explore…
As I said with my second edit , without a clean install , when I let the GUI make the update , it’s all right for my suscription , even if I don’t know why after 5 new clean install Avast doesn’t want my license key.
However , it’s mainly about the second issue (web shield disabled) I am worried
