I have removed the 2 log files as advised.
I currently have 12.0.6.1 and when I click on "Update Now" in the update window, the "Status" immediately switches to "Failed" and the window closes.
No files get created in the updateLog folder so have sent the below hoping it will help.
LiveUpdate.txt last entry is:

There is also a LiveUpdate.log.lock file in Dcocuments/DVDFab.
