Fix: You are trying to run the x64 installer on ARM64. Download the explicit ARM64 MSI from the SEPM console under "Client Install Features" > "Windows ARM64 Client".
Status: Native ARM64 support is available (but hidden).
Since SEP 14.3 RU8 (August 2023), Symantec has included an ARM64-native installer for Windows. It does not advertise itself loudly, but the file exists within the standard SEP package.
The "Hot" factor: Early versions (14.3 RU1-RU7) ran under Microsoft’s x64 emulation on ARM. This caused delayed real-time scanning and a 15-20% performance hit—hence the "hot" (overworked CPU) complaints. RU8 fixed this natively.
How to deploy to Windows ARM64:
Historically, SEP clients were designed for x86/x64 architectures. Running them on ARM64 devices (like Windows on ARM) previously required using x86 emulation, which often resulted in poor performance, high battery drain, and inconsistent protection.
Current Status: Broadcom has released Symantec Endpoint Protection (SEP) 14.3 and later versions with native ARM64 support.
The keyword "Symantec Endpoint Protection arm64 hot" points to a real pain point—enterprises trying to secure next-gen hardware with legacy tools. Here is the executive summary:
