  • Modules update failed: "Your license file does not contain a Username or Password. You can update only from an update mirror."

  • ESET LiveGrid® is not accessible: “The credentials used to access ESET LiveGrid® servers are not correct.”



If endpoints are not upgrading correctly to version 6.6.2072, follow the instructions below.

  1. On the affected endpoints that have not upgraded to version 6.6.2072 successfully (use RDP to check remotely), from the main program window click Update → Show all modules. If the module list is empty, restart the operating system. 
  2. Send an upgrade task to clients without selecting an ESET license (if you are running an upgrade installation on a previously activated product, do not select the license). 

    Make sure to select the check box next to Automatically Reboot When Needed.
  3. If the installation is still corrupted, use the ESET uninstaller tool and install again. Do not uninstall ERA Agent.
