Run syncthing-1.27.2-setup.exe again, making sure to select a non-administrative installation.
That way Syncthing will run under user “chris” and have all of the necessary permissions to access files under C:\Users\chris\AppData\Local\VirtualDJ\.
At first it didn’t work, but that was my fault, as I still had the old PC set up on the laptop-syncthing. After deleting that over there I was able to set up properly. Just putting it out there, so that other users may be shorten their troubles.
