If the installation of FineReader Server 14 has been finished unsuccessfully, starting from the version 126.96.36.199 you can save installation logs from the installation dialogue.
Logs are saved in form of a *.zip archive and contain *.txt log files. Error messages in the *.txt files can be analyzed to solve the issue.
For example, if in the logs you see the following error message:
Abbyy.FineReader.Server.Setup.UI.Model: *** ERROR: An error occurred while installing or initializing the program: No action was taken as a system reboot is required.
You would need to reboot the system and launch the installation again.
If you are facing difficulties analysing error messages, make sure to attach the installation logs to the support ticket.
