that didn't work for me. no copy exists in my purchases. maybe since it came on my computer and I never had to purchase it from iTunes store?
found another solution elsewhere that did work.

There's a workaround/hack that will let users run iPhoto 9.5.1 and later on 10.10.3.
1 - open the iPhoto application package by Control (right) - clicking on it and selecting Show Package Contents from the contextual menu.
2 - navigate to the Contents/MacOSX folder.
3 - make an alias file of the iPhoto file inside that folder and move it to the Desktop.
4 - to launch iPhoto double click on the alias file. It can be placed anywhere on the hard drive and dragged into the Dock for convenience.
Notes:
1 - the Terminal application will open and must remain open while you're using iPhoto It can be hidden so it won't get in the way.
2 - I've tested this with both iPhoto 9.5.1 and iPhoto 9.6. It does not work with earlier versions.
Thanks to user Todd Dixen for this tip.
