How to update from pre App Store versions of iPhoto to iPhoto 9.6.1
After updating to Yosemite 10.3.3 from Mavericks my old iPhoto '08 v7.1.5(378) copy of iPhoto is grayed out with the circle/bar through it. I can use Old Toads package contents workaround to run it; but would like to not have to use that workaround each time by updating it to 9.6.1
All the posts I've found about updating to 9.6.1 use the App Store purchases list; but since that/my version of iPhoto was not purchased using the App Store, and iPhoto is not listed or hidden in my App Store Purchases list, those methods won't work for me.
Is there anyway to upgrade from my iPhoto '08 v7.1.5(378) to iPhoto 9.6.1? Or from iPhoto9.4 which is still available from Support/Downloads?
