Most newer add-ons are supported by Aerosoft One at the time of release, however, this may not always be the case.
You can see if an addon is supported by Aerosoft One by going to the respective addons page. If an Aerosoft One symbol is shown, the product is supported by Aerosoft One.
You will still be given the option in Aerosoft One to start the installation of unsupported add-ons. These will be listed in your library under "Other Add-Ons", where you will then be redirected to an external installation.
