The "Beta 9 has expired" error is symptomatic of a larger issue: abandonware. QualityWings, once a titan of flight simulation, has not released a product update or official statement since 2020. Their website remains up, but support is effectively non-existent.
For users migrating to Microsoft Flight Simulator 2020/2024, the news is grim: QualityWings has never ported the 787 to the new sim. Instead, the market has moved on to developers like: beta 9 has expired qualitywings 787

The Beta version is not intended for permanent use. The developer eventually released the "Gold" or "Release" version of the QW787.
Some users who originally bought the full version have reported this error after a Windows update or a registry cleaner tool accidentally deleted the activation proof. The QualityWings 787’s internal systems fall back to a "beta mode" if the main license is invalid. If that fallback mode is an expired beta branch, you get the error.
Many simmers keep backups of old installers on external hard drives. If you recently reinstalled FSX or P3D and dug up a file named QW787_Beta9_Installer.exe, you are installing an expired product. The server-side authentication fails because the beta period ended long ago.
