Why is Extension Manager choking on installing Adobe CC Libraries 11.5 on AI 18.1.1?

Question

The error window states it requires AI v. 18.0 - 18.9. I am running v18.1.1.
The first error I found was an entry on the Creative Cloud app stating "The Add-on Creative Cloud Libraries installation failed because it is incompatible with installed... " The message concluded saying to "click here" which actually led nowhere. This message appeared the day I converted my LR to the CC version - that project appeared to complete successfully.
The puzzle is enriched as there is a Libraries Panel visible and functioning in my AI right now despite the error message.
Suggestions?

Hi Doug,
Thanks for the updates, I'll try to deal with each of your points as best I can.
It's expected that, for example, Lightroom is not listed in Extension Manager while Photoshop is listed. The reason for this is that some applications (such as Photoshop and Illustrator) have support for standard Adobe CEP extensions and are listed in Extension Manager, while others (such as Lightroom) do not, so they're not listed. For the sake of convenience, with applications such as Lightroom that Extension Manager doesn't fully recognise, it can still install extensions for them using ZXP packages prepared by the developer - but the extensions will be listed under "Others".
Thanks for the feedback about error messaging - I'll pass this on to product management so it can be taken into account in future.
Built-in components such as Kuler and CC Libraries are kept up to date using the Adobe Add-ons part of the Creative Cloud app. Whenever a new update is available, it will automatically be downloaded and installed through the Creative Cloud app. If this was failing (as sounds like was happening for you), then inside Photoshop you'd still see Kuler/CC Libraries but they may perhaps not be the most up-to-date versions of those panels.
If you manually install a ZXP package via Extension Manager with the same name as a product already installed, then Extension Manager will see it as a conflict and give you the option to install your new one over the top. As long as the new ZXP is compatible with both applications (Photoshop and Illustrator) then it'll be installed for both.
I don't quite understand your installation problems for the Magic Picker product. Do you mean that it installs successfully for Illustrator CC 2014 and Photoshop CC 2014 (including appearing for those applications in Extension Manager), but it doesn't appear under Illustrator CC? If the compatible application is listed in Extension Manager and Extension Manager is showing the extension as installed, then this may be a question for the producer of Magic Picker.
Best regards,
