You are running the Aperture Trial installer, right? This will install Aperture 3.1, and that is incompatible. You could then try to install updates from Apple's Support page, but they will only take you to Aperture 3.4.3.
The aperture versions, that require a registration key are no longer supported for updating at all.
All later updates are only available, if you have an App Store version of Aperture installed, not the Apple Store version, that requires a registration key.
It was possible to convert the licence to an AppStore licence, when MacOS X Mavericks was released. You missed that window of opportunity unfortunately. Now it is too late, because Apple stopped the developement of Aperture and only reinstalling AppStore versions is supported.
Your only chance is to contact the App Store Support and talk them into providing a redeem code for an Aperture 3.6 download, to be able to update. This will not be easy. In some cases the AppStore support helped.
so I am seeking advice and I hope to ask my question in as intelligent a way as possible - to match the intelligence of your advice
CURRENT situation: I am an Aperture 3.6 fan using it on an iMac (mid-2010) running El Cap. I shoot RAW files and have just moved from 16 MP camera to 21 MP camera so will start chewing up space even faster so I plan to move to a dedicated photography machine (used Mac Pro ...) and let the family keep using the iMac.
I want to extend my use of Aperture a few more years until Photos.app catches up or move to another solution like CaptureOne...
I started with Aperture on my iMac in the Aperture 2 days and have been upgrading ever since.
WHEN I do get my used Mac Pro (6 core, lots of RAM Radeon HD 5870, SSD) -- I'm open to your hardware configuration advice too BTW ) can I easily move Aperture 3.6 over? and How? (no need for great detail just approach like - load and upgrade or copy over or use migration assistant [which I think won't work because it wants to move everything?] ...) Do you recommend a certain OS X version to use on this dedicated Aperture machine?
