On Windows agent endpoints auto-upgraded from Symantec Endpoint Protection (SEP) 14.3.x to SEP 16.0, the following status is displayed in ICDm console:
Security Status : Compromised
Security Status Reason : OS does not support Trusted Signing (Feature Management)
Both SEP 14.3.x and 16.0 system tray icons are displayed simultaneously.
The SEP 14.3.x GUI appears normal.
The SEP 16.0 GUI displays "Error upgrading". Clicking the error reveals the following message:
Symantec Endpoint Protection can only be installed on systems with Microsoft Trusted Signing (formerly Azure Code Signing) support. You must install the appropriate Windows security update for this system.
This issue is resolved in ESA version 2.8.0.31. The agent now prevents upgrades to SEP 16 on systems that are non-compliant with Trusted Signing.
Please also refer to Unexpected OS restart requested after LiveUpdate on SEP 14.3.x.
Please perform the following steps to uninstall SEP 16.0 and ensure that only SEP 14.3.x continues to operate.
