am using an OS X Mavericks iPhoto 9.4.3 and trying to install iPhoto 9.5.1 - but when I load up iPhoto 9.4.3, it states that I should update to iPhoto 9.5.1 - I click "Go to Software Update", am booted to the Mac App Store, then it doesn't show iPhoto 9.5.1 as an available download.
I went the route of Ask Different iPhoto 9.5.1 upgrade thread and deleted the com.apple.storehelper/* but that didn't help. Then I went and deleted iPhoto.app. Big mistake. Now I'm unable to download the app from the Mac App Store (it states "Newest version of iPhoto is for OS X Yosemite only - want to download the previous version?" I click yes and am told "Mac App Store error (null)" and that's it.
How should I proceed? I was able to find a downloader for iPhoto 9.4.3 from the Apple Support pages - and am hoping that it will at least let me re-install iPhoto 9.4.3, but getting to iPhoto 9.5.1 would be pretty important right about now.
(background story, trying to upgrade library to iPhoto 9.5.1 so I can boot up iPhoto 9.5.1 from another Mac and combine / merge it's iPhoto library and the 9.4.3 iPhoto library -- since I'm doing a massive 3 machine 3 iPhoto library merge + duplicate check work for a friend)
