So I updated to 10.10.3, and opened the Photos ap, and let it import my iPhoto library. Everything seems to have imported alright, but I can no longer open iPhoto. Every time I try I get this error. It is the latest version of iPhoto, and it worked before the update. I know because I opened it to see how may photos I had, to make sure the Photos app imported all of my photos.
And yes I tried clicking "search the app store", you can't even download iPhoto anymore
