Where is the user.con file in Windows 11?

Age of Empires III: DE III - Discussion

I was told to go to:

C:\users<your user name>\Games\Age of Empires 3 DE<Your steam profile ID>\Startup\

But after \Age of Empires 3 DE\ there is no steam user profile id - just ‘common and log’.

???

common should be the next step
