File this one under "Oh my god I will seriously jam this pen in my eye."
About a week ago I noticed a warning from Symantec Endpoint Protection telling me virus definitions were out of date. (I am running Windows 7 64-bit, incidentally.) Running LiveUpdate manually threw an error. Err, what?
So, suspecting some form of abstract corruption, I used the Symantec Cleanwipe Tool to remove all traces and reinstalled. No dice. The installation would get only so far and then roll-back with an annoyingly non-specific error.
I tried many fixes, finally found the right one. The problem with the aborted installation and the original failure of LiveUpdate were related to a DCOM conflict. Solution is detailed here. I have a feeling if I had known I could have implemented this solution without re-installing SEP to begin with. Argh.
