Direct Download Links https://prodesigntools.com/tag/ddl MAY help
-you MUST do what it says in Note: Very Important Instructions
-https://prodesigntools.com/adobe-cc-2015-direct-download-links.html#download-instructions
-the prodesign links go directly to Adobe's file server, so this process
--will only work until Adobe completely removes the old version(s) from the server
.
When you do have a download, be sure to copy it to at least one external device
-a usb flash drive or hard drive, or write to a DVD
-plus a text file containing your serial number
