Sorry took a while to find time to have a closer look. Thanks for the suggestions. I seem to have resolved the issue. Duplicati would run normally from the system tray-icon with out the service but would not run as a service. I tried everything like removing Duplicati files and folders. And reinstalling all software. Nothing worked. I decided after uninstalling Duplicati and removing the service to search for the registry for any mention of Dupicati and deleting those entries. After a reboot and reinstalling Duplicati and its service it worked! I took a backup of the registry and might be able to list the entries if anyone thinks it will help but doesn’t look like it a common problem.
