All of my Aerosoft aircraft show up in the updater, but none of my scenery.  I have a few friends who've told me that they have their aerosoft scenery there as well.  I cannot figure out why mine isn't appearing.  Is there a way to rescan my system or however it finds it so it keeps my scenery updated as well?

Only products are are specifically included will show up. This means almost all release from 2019 till now and most products which are updated in that period.  We are not making new installers for the older products to include them.
