Can you post liveupdate logs?

The chances of the scheduled liveupdate not working are when the start time and the end time are the same for the hour and the minute and the schedule is daily.

Change the end time to atleast 2 minutes to end, but good practice is a difference of around an hour between the start and the end.

It's because since seconds are not the criterion thus its picked up randomly for the minute and since it would put it out of range for the end time, Liveupdate would not run and would be scheduled for the next day and the same thing happens again.

how to attach files here ? thx 

OK already attached the log files. 

As per my analysis of ur log i guess you will have to clear all previous logs of liveupdate and re-run the LUALL. Return code 100 has been found in the logs. Check that u r not runnong lack of space. 

you are using SSC ver 9 so I guess you are on SAV CE 9.
this version is no longer supported (End of Support Life: March 31, 2009)

The version you are using is older one & is no longer supported.
Update it to latest one

If you are using an older liveupdate then you may download the Lusetup.exe file. Save the file to a location on the hard drive. After the download is complete, double-click Lusetup.exe to install it. Restart the computer. Run LiveUpdate once. This may solve the problem.
