Can I get Installer for Aperture 3.6? Apple terminated Aperture at 3.6. Photos.app is the only replacement, for my uses it's far from ready. I want to be sure I can run Aperture 3.6 for at least 2 more years. I'd like an installer.

We have been able to download from the app store, but yesterday Apple transiently removed Aperture from our Previous Purchase list. (It's now back.) Aperture 3.4.5 updater is the last version available for downloaded from Apple [1]. No-one I know trusts Apple to keep Aperture available.

Does anyone know a way to get the Aperture 3.6 installer? How about a way to restore Aperture to a new machine from backup?

I have a license of course.

I updated from Mavericks to El Captian and suddenly Aperture 3.4.5 stopped working. Sadly, the Aperture 3.6 update is not available in the App store. Don't know if this is a temporary thing or it's gone forever. However, if you have 3.6 on another Mac you can drag the app itself to a flash drive and simply drop it in your App folder. It did it today and it runs perfectly under OS 10.11.
