In Design - Crash on startup : EXCEPTION_ACCESS_VIOLATION
I've been struggling few months with this error when starting In Design .
And this happens on mutliple computers , different hardware and same OS (Windows10) , and only In Design fails, other Adobe products works.


Spend hours with Adobe support on the phone and their only answers is usually to uninstall the product , delete pref & try again. And then no more answer from 2nd line support for weeks....
I FINALLY manage to get to a solution , after spending ages running tests (Not to mention we pay a fortune for those products, and then you have to figure out the solution by yourself, and eventually be nice enough to post the solution for others.....)
There are files inside Appdata\Local\Adobe , that are blocked by our Antivirus (but without any error messages, otherwise it would have been to simple) , and i'm not talking about admin rights there...
SOLVED :Create an anitvirus exception on the following file : C:\Users\%username%\AppData\Local\Adobe\InDesign\Version 15.0\AdobeWLCMCache.dat
Let's be clear , removing a complete folder from the Antivirus is not a safe or viable solution .
I hope we'll get a fix one day.
