ESET Bridge installation troubleshooting


oIf the installation is unsuccessful, review the installation log files in the All-in-one installation package. The logs directory is the same as the directory for the All-in-one installer, for example C:\Users\Administrator\Downloads\x64\logs\

oVerify that ESET Bridge services are running in the services.msc snap-in (look for EsetBridge and EsetBridgeWatchdog).


oVerify that the EsetBridge and EsetBridgeWatchdog services are running by executing the following commands:

sudo service EsetBridge status


sudo service EsetBridgeWatchdog status



By default, both services start automatically. The EsetBridgeWatchdog service monitors the EsetBridge service and restarts it when it stops.

Restart the EsetBridge service remotely

You can restart the EsetBridge service remotely from ESET PROTECT Web Console using the Run Command Client Task:

Windows: cmd /c "net stop "EsetBridge" & sc start "EsetBridge"

Linux: sudo service EsetBridge restart

Windows: C:\Program Files\ESET\Bridge\pkgid

Linux: /opt/eset/bridge/etc/pkgid
