Without proper system info and technical details like the crash logs nobody can say anything.
Mac Pro mid 2010, 2 x 2.4 Ghz Quad-Core Intel Xeon
New Mac Pro 2014, 3.7 Ghz Quad-Core Intel Xeon ES

We were not able to get any crash reports - that option not available; the spinning wheel was coming on and off, but nothing would happen and nothing could be done, but re-start machines.
Have cleared prefs files since, this a few times. Based on suggestions found from others having the same problems.
After clearing prefs files, worked awhile , then the same happened.
Hope this helps.
Moving this discussion to the InDesign forum.

We have tried to install the previous version of InDesign CC but that is no longer (conveniently for you, nightmare for us) available.
Perhaps you are suffering from insufficient permissions. see Cant launch new inDesign CC | Adobe Community
Sorry, posted before finishing the part relevant to the quote. If the CC App is up to date you can scroll to the bottom, show other applications, and filter to show older versions.
InDesign did launch, we didn't have the message as the other post "Can't launch InDesign . . ."
We cleared the prefs and it was working for awhile, then same thing happened. When Indesign was launched, existing foe was opened from within InDesign, the spinning wheel would come on and not allow any work to be done. No crash report option was available.
If trashing the prefs is effective for awhile, you probably have some sort of software conflict on the system.
I have heard of a conflict with InDesign and DropBox, are you running that software by any chance?
Did this issue get resolved?
