Even running a simple Symantec Live update can have issues! Bloody computers, anyway, when doing some simple maintenance and I receive this error:

“LU1805: Liveupdate was unable to find any products to update”.
There are no products on this computer that can be updated by LiveUpdate.  —- ( ahem! I beg to differ Sir! )
bex-lu1805

Resolution:
Open up a command prompt and type:
“C:\Program Files\Symantec\Backup Exec\BeUpdateOps.exe -AddBE –OptOut”   (File Location may Vary)
16_01_2014_001

You should then receive this:
16_10_2013_004

Now you can now run live update without any problems, Ta Da! :
16_10_2013_005

Hope this gets you out of a sticky Quibble.
