My processor does not support SSE2 instructions set

bonjour,
j'ai besoin d'installer AVG Internet security sur mon ancien ordinateur.
Hélas, j'ai un message qui m'indique que je ne peux le faire car mon processseur ne supporte pas SSE2 instructions set!
Comment puis-je faire pour installer AVG sur cet ortdinateur?
Merci
