I am trying to upgrade my various iPhoto libraries I have had over the years. My libraries under iPhoto '09 upgraded like a charm. However, when I try to upgrade older libraries, iPhoto '11 asks me to install the iPhotoLibraryUpgradeTool, of which I presume is already installed since iPhoto '11 can already upgrade '09 photos. Any suggestions as to upgrading older libraries into iPhoto '11 would be much appreciated. Thx.
