Can not add-in endnote

For the past few days, I have been unable to use Microsoft Word reliably because the application keeps freezing.

I contacted your Microsoft support team, and the issue was reportedly resolved by updating my registry.

After this, I noticed that I’m no longer able to use the EndNote add-in / “Cite While You Write” functionality. I upgraded my EndNote to the latest version, but I still cannot configure it in Word. When I attempt to set it up, I receive the message stating that “the current Word is not supported for EndNote.”

Could you please advise on how to fix this? If the registry update may have affected Word’s add-in compatibility, I would also appreciate guidance on what needs to be changed to restore EndNote support.

Thank you for your help.
