Save and Transfer My Settings?

In trying to update, I’m told Scrivener is not running from last installed location, delete all copies not in installed location. This means the extensive appearance changes I’ve made will also be deleted.

Is there a SETTINGS file I can copy from this copy of the program, and then insert into the newly-updated version?

Alternately–why can’t I just update the copy I’ve apparently been using all this time, instead of reverting to the one in the ‘last installed location?’

Thanks for any help!
