How do I backup my custom exeptions and settings on an unmanaged client?

Hello! I'm using an unmanaged client. A few days ago, I started getting the message "Proactive Threat Protection is not functioning correctly." I've tried using SymDiag.exe, and updating from 14.1 to 14.2, but nothing I try seems to fix the error. I'm just going to try uninstalling and reinstalling Symantec, but I have a lot of custom settings and file/folder exeptions that I don't want to redo. I know that with SEP Manager, you can control and backup these settings, but I can't seem to find any info about an unmanaged client. Is there a way to backup and restore these setings after I reinstall it? Do I need to install Manager, backup my settings, reinstall SEP, restore my settings, and uninstall Manager? Thanks!
