Ok ok I understand my friend,
I don’t really know how to do it (me I’m under MsStore) I think there was a bug with the path seen that steam told you that games were uninstalled but it was still present in the folder and as you deleted it yourself it could be uninstalled before … otherwise ask directly to MSFS via → https://flightsimulator.zendesk.com/hc/en-us Good luck man
