I can't find a serial number for the 777 Worldliner Proffesional-extended pack.

Question

In order to resolve this problem will I need to buy the non extended version in order to use the plane or not? In the download it states the following serial="NO-SERIAL-USE_FROM_ORIGINAL_777_ORDER."

Answer 1

The 777 is a third party plane, not created by Laminar Research. If you have lost your serial number to unlock the plane, please contact the store you bought it from (x-plane.org, etc).
