After the automatic upgrade to 15.17, word 2016 cannot be used any more. Crash within seconds. CWYW seems to be the problem!
I apologize for the long delay on this post.
At this time the Beta Cycle is over so you will want to uninstall the Beta and install the full version of EndNote which is compatible with Word 2016 now.
Please contact us again if you have trouble once the full verson is installed.
