It does show up in Content Manager as Installed in Community folder.
I can’t figure out how to update, and I’m certainly not buying it again.
steam installs Crj500/700 to …
C:\Users\your drive\AppData\Roaming\Microsoft Flight Simulator\Packages\Official\Steam
I updated from market place, it just re-loaded over and over again,
I deleted this directory … C:\Users\your drive\AppData\Roaming\Microsoft Flight Simulator\Packages\Official\Steam\aerosoft-crj
and this one ,C:\Users\your drive\AppData\Roaming\Microsoft Flight Simulator\Packages\aerosoft-crj
restarted MSFS , and download from market place, and it worked fine
cheers
