Re install ilife 06 after Leopard erase and install

Hi there,

So I bought my Mum 10.5 for crimbo so she can run it on her intel macbook which had tiger and ilife 06.

I did an erase and install of Leopard, everything is fine.....apart from that I can not re-install ilife 06.

I insert disc 1 that came with the macbook I think they are the restore discs that has tiger on it. I choose "install bundled software only" and it says this software cannot be installed on this machine?

I have searched google and these forums but have not seen any similar threads....

Any ideas would be great.

Thanks

Alex
