iphoto damaged or incomplete
I purchased a MBP in late 2011 from the Apple Store. All software was loaded and no discs were included with purchase. It did not include iDVD so I installeled iLife to get it but now when I try to open iPhoto I get a message "You can't open the application "iPhoto" because it may be damaged or incomplete. All other iLife apps are fine so I'm assuming the iPhoto file on the iLife disc is corrupt.
Since I purchased the computer with iPhoto already on it I should be able to restore it. How do I do that wihout a disc? What is the method for restoring pre-installed software where a back up disc was not included with purchase?
Thanks
