I did a clean install of lion. However, I completely forgot about needing to reinstall ilife/iwork. Prior to upgrading I backed up my mac with superduper. I located my iWork disc and applications install disc that came with my 2011 MBP. I was able to reinstall iWork. However, i was hesitant to use the applications disc to reinstall iWork because when I launched the installer, it shows icons for applications like spaces, time machine, etc. If I run the applications install disc so I can get ilife back, will it overwrite all my Lion applications with my snow leopard applications? I urgently need iPhoto by tonight for a conference, if anyone could please help me it would be much appreciated.
