Not sure if this is only for a Creative Cloud client on a Mac.
The two most recent Adobe Flash installations have wrecked Safari browser tabs and wrecked recent "window" content.
On this basis, Adobe Flash will NOT be updated again.
Even more, the Adobe Flash install process pops up with a dumb Join Creative Cloud "offer" and that is something I find totally pointless.
In short, Adobe appears out-of-touch with modern web practice.
Don't wreck my browser and especially don't replace my previous browser content with an advert for a service I already pay for.
Also, I find it interesting that Adobe hide behind forums, rather than allow a person-to-person discussion via email.
