Hot to fix the Unknown error detected. Exit code is: C0000409 in Scadapack workbench
The possible workaround is to delete the files "*.acfmlge" and "Output-Build.txt" under the project folder.
Build the project and it should be successfull. If the problem re-appears in the future, delete the files again.
