After many failed attempts I re-read your suggestions and meditated what could be happening. I realised that there were old folders of adobe in my computer, as I had migrated everything from my previous computer. I tried to uninstall, unsussesfully (it requested to install Rosetta to uninstall).
After being frozen for a few days, not knowing how to proceed I took the "wild card" of simply DELETING ALL ADOBE folders in my computer.
Then after emptying the bin and re-starting the computer I proceed from zero, following your insights:
- Installing Creative Cloud
In doing so I got some error messages, that I just ignored.
Creative Cloud installed and reported and installation error, it suggested me if I wanted to "repair it" and I said YES.
It itself re-installed Creative Cloud using a different installer process and after a while - it appeared as if nothing was happening - Creative Cloud opened. YEAH!!!!
