I have the same problem others seems to have. Like this one: Indesign has Stopped Working
My Indesign CC 2015 all of a sudden crashed yesterday, and after that it crashes when I try to launch it.
I tried to follow this steps mentioned in the other thread: InDesign crashes on launch on Windows
But it doesn't help. Indesign still crashes.
Crash on launch after a previous crash probably is the result of corrupt recovery data and you need to empty the InDesign Recovery folder. If you're lucky the file that crashed will still open at the last saved state from the File > Open.. command. See InDesign crashes upon launch while attempting to recover a damaged document
