In the GUI for Symantec Endpoint Protection Manager (SEPM), on the Details page for a Win10 client-64, SEPM reflects that 64-bit is "yes".
In the GUI for Endpoint Detection and Response (EDR) appliance console, on the search results or entity page for a 64-bit Windows endpoint, EDR displays a 64-bit state of "no" for the same endpoint.
Broadcom Engineering resolved this issue in version 4.5.0. Please update to the latest build to receive this fix.
