I have iphoto that comes with my macbook pro. It used to work but since some day it stopped working. I checked my Application/ folder and it's gone (maybe I mistakenly deleted it?). Anyway I checked Trash it's not there either. I tried to re-install iphoto and got the following message The installer could not locate the data it needed to install the software. Check your install media or internet connection and try again or contact the software manufacturer for assistance Anyone could help?
