Not sure about subscription versions, but with QW2017, the file EmergencyRecordsOrganizer.exe is in the C:\Program Files (x86)\Quicken folder.
The topic does come up here periodically - how best to set up your finances and convey necessary info to loved ones in the event something happens to you and they need to step in to manage your finances.
The Emergency Records Organizer was quite helpful in collecting the necessary info. I believe there are other such organizers available, but being able to get at least the one time sync of info from Quicken to the ERO was a plus.
Go to View and select Classic menus
Then the ERO is under Property & Debt.
If you click on it and the ERO is not installed, it will be installed.
It is a 1-time data sync and it appears the data is global, not specific to the QDF file that is open.
You ran the install on the current version? I am on R48.15 and I have it under Property & Debt. Also, are you saying there is no Property & Debt dropdown? If so, then you should go to View and select "Classic Menus" and you should see more dropdown menus.
