The work around is to use an older version of After Defects like 4 which boots fine and jolly. CS6 works in Sierra perfectly, including Photoslop. A lot of money spent on not being able to use the program. Sorry I write directly to you, but I find it very difficult, no - impossible to reach any help from any Adobe-employee. But the system must be able to see that it's the same computer? Do you know if it is completely impossible to get it back? I installed in on my old mac and then this mac - so i used my 2 downloads.
I have done as former posts recommend Log-ind and click the small box for downloading Illustrator on my computer, but right before it comes up with an 'Error number xx' (can't remember it right now). Last time a guy from India wanted me to download something and pay him money for the download. I was wondering if you could help me getting back my Illustrator? (my absolute favorite) I accidentally deleted it from my computer and when I look up in Adobes forum about this I run my head against the wall. I have a problem with my Adobe CS6 package, which I also many years bought and installed.
