The warning "The project was created by a newer version of ABBYY FlexiCapture" appears on the Project Setup Station:
This behavior is caused by a difference between the FlexiCapture12 build with which the project was originally created and the current FlexiCapture 12 build.
To resolve the issue, it is required to upgrade the current FlexiCapture 12 to the same (or a newer) version as the project was originally created. It is recommended to follow the steps from the article "Updating ABBYY FlexiCapture 12".
