Are you logged in with a regular user account, or a user account that's an administrator on the computer?

Thanks!

Ok, could you do the following?

- On the Troubleshooting tab in the DisplayFusion settings, check the box to enable Debug Logging and Apply the changes.
- Click the Open Log Location button to open the folder that contains the DisplayFusion.log file
- Try to enable the Windows Logon Background setting and note the time that you attempted to enable the setting so that I know where to look in the log
- Email me the info from the Troubleshooting tab (you can just copy paste) as well as the DisplayFusion.log file and the date/time that you tried to enable the setting

Thanks!
