Live Update - Unknown Error

Happened to notice that Live Update had not run in several hours, so I attempted it manually. This is the error I am continually getting every time I re-try to manually update. I have run Support; found & fixed one error. Same result. Ran Support again; no errors. I re-booted. Ran Live Update again; still seeing this error. Task Bar icon is OK w/ green check. Windows reports nothing . So, it all looks OK except for this error message ... don't know.
