32 bit ot 64 bit Mac OS update v9.3

I did something stupid I guess by looking for updates for Endnote in Mojava. It did not find any and then installed Catalina, despite the message that Endnote would not be running anymore. Now I downloaded the update manually but it can’t fnd endnote anymore. Is there a solution? Thanks a lot for taking the time to answer my question.

Kind regards, Sebo
