Maybe this is common knowledge, but after updating to the latest version of Muse (2017) and discovering it will not launch, i've reverted back to the (2015.2) version.
So Creative Cloud is all about having the latest versions of the Adobe products available to download. Clearly this isn't the case.
Even the experts at Adobe who took control of my Mac today didn't have a clue either saying it's a problem that my Firewall was corrupting the update.
At what point in time will the other products cease working on older operating systems!
