Thank you very much for your quick answer JJMack! I am not a tecnical type (besides I am not eaven a native speeker of English) but as far as I know my sistem, OS X El Capitan v. 10.11.6, is updated. What you mean Activate CS6 with my serial? Should I just start it again somehow with the 24-digits serial number, written on the software CD box, or delete the programe completely and louded it from the CD as I did the first time?
This is not an answer. I've been busy these days, here is my report. Fistly I try loaded my stand alone Adobe Design Standard CS6 right from the original DVD. It was surprisingly far from simple. Finally I somehow got something, sadly just the Photoshop. Then I started look after the Design CS6 in my Time Capsule and managed restor only the Illustrator. Well, better than nothing, but I badly need my InDesign too. After long hard work I eventually got it! I was enthusiastic, immediately started a document and got the message: Configuration error, Error 11. The application simply refuse to start. Any ideas? (OS X El Capitan 10.11.6, memory 12 GB) And one more thing, I installed a big antivirus program hopefuly turn my iMac to some sort Fort Knox, just in case.
P. S.: I do not used the Cloud, I never used a trial mode of an application, I never used any Creative Cloud software.
