Hi,

License error occurs in my standalone application on Studio2019 after upgrading license to 2021. Before upgrading license, my application works well on both 2019 and 2021.

Isn't 2021 upgrade license fully supported on 2019?

According to activation dialog on 2019, we can use 2021 upgrade license on 2019.

Unhandled Exception: Sdl.ProjectAutomation.FileBased.LicensingException: License check failed, with exception: Sdl.ProjectAutomation.FileBased.LicensingException: A valid SDL Trados Studio Professional license is required to use the Project Automation API in a standalone application.

   --- End of inner exception stack trace ---

   at Sdl.ProjectAutomation.FileBased.FileBasedProject..ctor(String projectFilePath)

My trados 2019 SR2 is 15.2.8.3007.

Best regards,
