I've recently bought X-plane 10 (version 10.42) on steam. Now I am willing to update to version 10.45 with the x-plane version on steam. Once I've updated it and I start x-plane on steam, it asks for a serial number. I've looked in my email and I cannot find any serial number. Where can I find it?


Best regards

Hi Lorenz,

Support for the Steam version of X-Plane is handled by Aerosoft. Contact them at for additional assistance. I was not aware that the Steam version used product keys. I thought your Steam client log in was your authorization for your purchases through Steam.

If you purchased digital download from, your product key should be in the email confirmation you received after your purchase. If you have lost it, please contact support at [email protected]
