G'day and welcome to the forums.

Helps greatly if you tell us about your computer and current operating system. We have to guess is it a Core 2 Duo, the minimum for installing Lion?

System

There is the info that i have on my mac :

2Ghz Intel Core Duo

Memorie : 1.5 Go 667...R2 SDRAM

Macintosh HD

Please help !

You can not install Lion on an Intel Core Duo as that is a 32 bit system. Lion requires a full 64 bit system for installation. That means a Core 2 Duo or higher CPU is required.

There is your answer. Lion for Core 2 Duo machines only. The latest OS you can install is Snow Leopard available for $29 still available from your Apple store on Apple Online.
