I've used Enpass a few years back and today I recommend Enpass to a friend.
Download the windows 10 application and

Create a second vault, first vault isn't being used yet, main purpose is to setup a second vault to share across 10 people.
Sync the second vault to Dropbox, with below error message:
Sync Error, Something went wrong while syncing with Dropbox Error code: 208409
In Dropbox, there's a new folder created, Dropbox\Apps\Enpass, with empty content.
I've never installed Enpass on this computer
