Issue/Introduction

The SESC console shows errors, "Error: Install script executable failed (215)", and "A LiveUpdate session encountered errors. # update(s) were available. # update(s) installed successfully. # update(s) failed to install," where # represents a natural number.

Cause

This is due to an AutoUpgrade package being successfully downloaded, but MsiLu.exe being unable to install the upgrade due to a pending reboot.

Log.lue (C:\ProgramData\Symantec\Symantec Endpoint Protection\14.3.4615.2000.105\Data\Lue\Logs\Log.Lue) shows 'package install failure code: -1.' indicating that a reboot is pending.

SEP_INST.log (C:\Windows\Temp\SEP_INST.log) supplies the detail: "Symantec Endpoint Protection has detected that there are pending system changes that require a reboot.  Please reboot the system and rerun the installation."

Resolution

Reboot the affected systems and allow the AutoUpgrade to complete.
