To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2. Download it from the App Store to reinstall It's on your Purchases List there.
For older versions that have been installed from Disk you'll need these additional steps:
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
2c: on 10.7 or later they're at
A Finder Window will open at that location and you can remove the iPhoto pkg files.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.

This didn't solve my problem. I moved iPhoto to Trash and insert iLife disk. It says my certificate has expired? Why? If you buy it - it should be good forever. So now what do I do??? HELP
