• Via the GUI: Click Help → Check for updates inside the ESET console. The product will auto-update the application components (not just signatures).
• Via ESET PROTECT: Create a Software Install Trigger in the dashboard. Set the target version to 11.1.2052.0 and schedule for off-peak hours.
• Manual download: Visit the ESET download portal (requires business login) for the offline installer named efsw_nt64_11.1.2052.0.msi. Do not use version 10 installers; they will not activate with new licenses.

Important: After updating, reboot is mandatory for the new driver (eamonm.sys version 11.1.0.5) to load. A soft restart without reboot leaves the old driver in memory, causing blue screens on some HP devices.

Deployment via ESET PROTECT (On-prem or Cloud)

The preferred method for businesses is silent installation using the msiexec command. For version 11.1.2052.0, the package ID is:

msiexec /i eea_nt64.msi /quiet /norestart ADDLOCAL=ALL LICENSE_USERNAME=your_username LICENSE_PASSWORD=your_password

IT admins can push the update from the ESET PROTECT console (version 10.0 or higher required). The upgrade preserves existing firewall rules, exclusions, and policies.
