Licence problem with Adobe Acrobat Pro
I have a problem with Adobe Acrobat Pro as a part of Adobe Creative Suite CS 6 on Mac OS X 10.11.6: Adobe Acrobat will not start. Every time I try to open a pdf-file or the programme (Acrobat) itsself, Acrobat appears inside the dock as well as inside the activity monitor for a few seconds, but never actually opens and then disappears from the dock and the activity monitor again. No error message shows up, to find out, what the problem is.
During the past two weeks I've tried basically all trouble-shooting suggestions I found on the web several times, mainly:
- Trying to de-install and re-install Adobe Acrobat by itsself as well as the whole Creative Suite (of course, using "Adobe Installers")
- Running the Creative-Cloud-Cleaner on my computer after de-installation and before re-installation
- De-activating and re-activating my Creative Suite licence (using InDesign to perform this task, since Acrobat will not open)
- etc.
Funny thing is: when I try to deactivate the licence via InDesign, Acrobat will not even show as one of the programmes involved, see screenshot attached.

That is why I think, the problem might be a licence problem. The reason, why I got the problem in the first place, might be the following: I accidentally de-installed Adobe Acrobat while being offline. After that, as mentioned above, I tried to de- and re-install the programme and the whole suite several times while being online - but no result.
I am glad for any suggestions. Since Adobe phone support does not seem to be available for this product and I kept being redirected to this forum when trying to start a support chat with Adobe, I am glad for any help from the community!
PS: I guess, this is not relevant, but I'll mention it anway: Another App, "Adobe Crash Demon" shows inside the Activity Monitor, everytime I open InDesign (but NOT, when I try to open Acrobat). The content of the error message does not mention Acrobat.
