We are in the process of trying to upgrade all of our SAV 9.0 Corporate clients to SEP. We have SEPM 11.0.4000.2295 installed. We have created a package that uses a silent install, no reboot and does not install Network Threat Protection.
When I push the package to a remote client running 9.0, either by using the SEPM or the Migration wizard, the install fails. The remote client does receive all the install files which are located at C:\Temp\Clt-Inst but the upgrade fails. I did a search on the remote client for any log files but there were none. Windows event viewer shows "The Windows Installer service entered the running state", then 5 minutes later..."Product: Symantec Endpoint Protection -- Installation operation failed."
If I change the package to a Unattend package and push it out to the same remote computer, it fails as well and I get a pop up message stating "Live Update is currently running. Please wait for LiveUpdate to complete before continuing" Also, if I do a silent install to a client local to the network here, it is successful.
To recap:
1. Client upgrade from 9.0 to SEP using silent install to remote network PC fails
2. Client upgrade from 9.0 to SEP using unattend install to remote network PC fails with LiveUpdate error
3. Client upgrade from 9.0 to SEP using silent install to local LAN PC is successful
Any ideas?
