if you have a cc subscription that includes flash (now animate), you're paying for flash pro cs6, flash pro cc, flash pro cc 2014, flash pro cc 2015 and animate pro cc.
you can use any one or any number of them simultaneously with your subscription.
so, there are a number of things you stated that are incorrect. that said, what is it that you want that you are unable to do?
The issue is that once the upgrade occurred, my Flash CC was deleted or overridden. It would not launch
and was no longer in ,u Applications folder.
1. when you install upgrades, adobe (unfortunately, imo) removes previous version unless you explicitly tell it to leave old versions alone (advanced options>untick remove old versions).
2. just past the 1/2 point down the page is a walk-through showing how to install previous versions, https://helpx.adobe.com/creative-cloud/help/download-install-app.html
