About 20 minutes ago I ran a manual LiveUpdate. It asked for a Reboot, which I did.
Another manual LiveUpdate downloaded a 10+Mb file, then asked for another reboot, which I did.
Another LiveUpdate then tried to install just the NIS Engine with the following error message:
Norton 2009 Product Update
Status: Failed to complete
The Tech Report doesn't provide specfic information beyond try LiveUpdate again, which I have a run few more times with the same result. I even ran it with Tamper Protection off, with no result.
