This is one of the reasons why I don’t like subscription model software:
We want to give you advance notice that upcoming versions of the Adobe video and audio tools will require Windows 10 (version 1709, or higher) or macOS 10.12 (or higher) to run. This applies to the next major releases of Adobe Media Encoder, After Effects, Audition, Character Animator, Prelude, and Premiere Pro.
Performance and stability are top priorities for all of our users. Running our apps on current versions of the Mac and Windows operating systems helps provide an optimal experience with our tools.
So basically if you’re on an older operating system and you still want to use Adobe CC Services you’ll have to pay a monthly fee for out of date software… Not that it matters to me. There are other pay and Open Source options that will do the trick in most cases, especially if you’re looking for encoders and video editors. This isn’t the early 90’s/mid 2000’s where Adobe was king, programs like Shotcut, Sony Vegas, and a few others are good substitutes. In fact I’ve been using Shotcut for over a year now, and only had to delve into Premiere Pro once to keyframe something (though I used CS6 instead of CC). All that I really use that’s adobe these days is Photoshop CS6, which will probably be my last version.
