-How to Extract the Library content to the Library folder
-Extract the zip file that you just downloaded. This will create a .7z file
-Extract the .7z file to create a folder based on the language you selected.
-Copy the contents of the language folder (eg. en-US) to the following location:
-Windows: C:\Program Files\Adobe\Adobe Encore CS6\
--Library folders will replace the existing Library Folders & Files
--Place into Windows: C:\Program Files\Adobe\Adobe Encore CS6\Library
--you will now see "many" sub-folders under the Library folder
Please, please, please, at the very least, keep the CS6 version of the software available to CC users for the next few years!
Adobe Creative Suite 6 FAQ
Under: "Upgrade eligibility, pricing, and purchasing options"
"Adobe will continue to make Creative Suite 6 available as a perpetual
software license, and will provide bug fixes and security updates
as necessary. All of the CS6 suite editions and individual products
continue to be available for purchase by Electronic Software Delivery
(ESD) on Adobe.com as well as through select retailers.
Volume licensing for these products is also available
through Adobe Authorized Resellers worldwide."
"We plan to sell Creative Suite 6 for use
on supported platforms indefinitely."
I'll give you a bit different presentation with some of John's same links.
The main link for Encore CS6 and its use in CC is:
(There is an announcement at the top of the Premiere Pro forum main page - one of 4 announcements at the moment - that links to that page.)
That page contains 3 important links:
Download and installation of Encore;
Functional content (in 2 steps); and
A CC/Encore CS6 workflow.
That page does not provide the FAQ link John provided that discusses the decision not to upgrade Encore to CC:
In the context of Adobe's commitment elsewhere to keep the CS6 apps viable [edit: Joe's post], we can assume that Encore will remain available indefinitely - unrevised and not updated for future operating systems. But it has not received the same support as other CS6 apps - and will not be updated to CC.
