Solution

Failed local installation of the ESET Management Agent

1. If you are running ESET Live Installer from a shared location, copy the live installer file to the local disk and attempt the installation again.

2. When you run the ESET Management Agent Live installer, right-click it and select Run as Administrator from the context menu.

Failed push (remote) installation of the ESET Management Agent

1. Verify that you have completed each step in the Remote installation requirements and checklist for ESET PROTECT and ESET PROTECT On-Prem.

2. Uninstall all other antivirus products before installing ESET and remove all files, folders and registry keys left by any previous antivirus products.

3. Disable the Windows Firewall on the server and client workstation. After installation, you can re-enable the firewall. See the instructions to disable the Windows Firewall.

4. Verify that the system drive on the target client workstations has enough free disk space for the installation.

5. Remotely deploy the ESET Management Agent.

6. If after following the steps above you are unable to push install due to the same error code, create a preconfigured Agent Live Installer file and try to install it locally.

Failed push (remote) uninstallation of the ESET Management Agent

Verify that you have included the necessary credentials with your push uninstallation package.
