How to know when the installation of the SEP and the download of the updates is complete

Hi all,

I use a solution that install automatically and sequentially some softwares. I need to know when the SEP 12.1 has ended the installation and has finished to download of the updates so that can start the installation of the next software.

With SEP 11 I was able to wait that the process “luall.exe” goes down, and then I knew when Symantec had finished the installation and the updates download. This process doesn’t exist anymore with SEP 12.1. 

How can I know when the installation is complete (without reading logs)? What check could I make?

Thanks
