When I am trying to export a project, using the 'ETS Project Exporter 4.1', there is the error “0x8000ffff (e_unexpected)” . The operating system is Windows 10. How can I solve this?
This happens when there is a file conflict during the export procedure. Close all the other applications running in the background and then launch this one again and repeat the export procedure. Make sure to also run the software as Administrator to give it exclusive access to system partitions if you plan to export on desktop or in any folder located on the system partition.
