[KB6745] How to re-deploy ESET Management Agent over an existing password protected Agent


User needs to reinstall ESET Management Agent over an existing ESET Management Agent which is protected by a known password.


  • The only type of installer where the password can be included is the Live installer script.
  • This solution works only on ESET Management Agent of version 7.x for Windows operating system.


To create an installer which can override a password-protected agent, you have to create a new (or modify existing) Live installer script.

  1. Create the Live installer script, but do not deploy it on a computer yet.
  2. Extract the downloaded file ESMCAgentInstaller.zip
  3. Open the ESMCAgentInstaller.bat in a simple text editor like Notepad.
  4. Find the section between lines 30 and 46 where the parameters shown below are selected.
