.. index:: engine only install :orphan: Engine Only Install =================== An **Engine Only Install** refers to a deployment method where only the core service executable (e.g., ``winsyslg.exe``, ``mwagent.exe``, ``evtlog.exe``) and its essential dependencies are installed, without the full client application and user interface components. This type of installation is particularly useful for: * **Mass deployments** where you want to minimize the installation footprint * **Server environments** where GUI components are not needed * **Automated deployments** where configuration is managed via registry files * **Security-conscious environments** where you want to reduce the attack surface In an engine-only install, the service runs with the configuration stored in the Windows Registry, which can be exported from a master installation and imported during deployment. This allows for consistent configuration across multiple systems without requiring the full installation package. Key characteristics: - Smaller disk footprint (typically just a few MB) - No GUI components or client tools - Configuration via registry import/export - Suitable for headless/server deployments - Can be updated by simply replacing the executable files This approach is commonly used in enterprise environments where hundreds or thousands of systems need to be monitored with consistent configuration.
