Programatically Check Symantec End Point Definition Date from current

I am trying to determine a way to programatically determine:

1. What the currently installed virus definitions are; My guess is:

Reg Key:" HKLM\Software\Symantec\Symantec Endpoint Protection\CurrentVersion\public-opstate

Name: LatestVirusDefsDate

2. What the current versions of the definitions are... no idea how to do this. This is probably less important, I just want to verify my definitions are less than X days old (which I haven't determined, perhaps 14 days to start).

3. How to trigger a silent live update programatically (no idea how to do this); Loose guess is:

C:\Program Files\Symantec\LiveUpdate\LUALL.EXE -s

... or some other command line switches.. but didn't seen anything.

Can someone provide some guidance?
