"word was unable to load an add-in" error message at launch of Word for Mac 15.25 despite update to EN 7.7

I never had any trouble to use EN for Mac with different Word 2016 but since updating Word to the 64-bit 15.25 version and despite updating EN to 7.7 (compatible with Word 15.25) I now for the first time get this weird error message at every launch of Word. After accepting the message, everything runs well with EN. I looked for an old "EndNote CWYW Word 2011.bundle" (this is the add-in that seems to be incompatible with Word 15.25 - according to the error message at lauch of Word)... but this old bundle had been deleted a long time ago... does anyone else experience a similar oddity? If yes, did anyone come up with a solution for it?

Ok, even though this seems odd... but it worked: I removed the EndNote CWYW Word 2011.bundle file in the /Application/EndNote 7/Cite While You Write/ folder. No more weird error message.

(The EndNote CWYW Word 2008.bundle file will also have to be removed.)

The accepted answer did not solve the problem for me. I still got the warning that an Add-In was unable to launch. Then I performed the following search:

sudo find / -iname '*CWYW Word 2016.bundle'

This found one file in

/Library/Application Support/Microsoft/Office365/User Content.localized/Startup.localized/Word/EndNote CWYW Word 2016.bundle

Deleting this then solved issue for good.
