For scripts to work in a Windows 7 64bit environment both these files must exist otherwise the script is not run. pre-backup is just the pre-backup.bat file without the extension.
/scripts/pre-backup
AND
/scripts/pre-backup.bat
If the first file is not present no script is run, if the .bat file does not exist but the one without an extension does Duplicacy says it cant find the script to run.
Using Duplicacy 2.0.8
Thanks
