I just updated to x8, after reading that this was the fix. I am operating on a MacBook Pro (Sierra 10.12.6) and Word for Mac (version 15.33).
I have completed uninstalled and reinstalled CYWY and Endnote X8 and this error persists "A COM exception has occured. Object has been deleted." whenever I click the "Update citations and bibliography" button.

Thank you for your assistance. While waiting for a reply, I copied and pasted, paragraph by paragraph into a new document. When I did this, I saw that a reference had been deleted, but a bracket was left behind (i.e., [ ). When I deleted this, the error was corrected.

I have the latest versions of Endnote (X8.2) and Microsoft Word for Mac (16.12) and everytime I try to add a new reference, the following error message appears "A COM exception has occurred. Cannot edit Range". Could you please help?
