  • SOLUTION: If you are installing ESET Remote Administrator on a server, make sure that you are logged into the administrator account while performing the installation.

MESSAGE: Uninstallation of the previous version failed. Please uninstall it manually and run the installer again. 

MESSAGE: This product version is not intended for server operating systems.

MESSAGE: Enter a valid Password to continue uninstallation.

  • SOLUTION: Your ESET product installation is protected by a password. Press F5 to access the Advanced setup tree, expand Access setup User interface Password protect settings and enter a valid Password to continue uninstallation.

    • If you do not know your user-defined password, use the ESET Unlock Utility to remove it and restore access to the configuration settings.


MESSAGE: This product version is not compatible with the installed version. It is therefore not possible to run the reinstallation. Please uninstall current product version and restart the installation.

MESSAGE: The header is corrupt.

  • SOLUTION: This error occurs when a user tries to decompress (unRar) the .exe installation file instead of allowing the installer to automatically extract the files. If you have downloaded an ESET product installation file from ESET's website, double-click the file to initiate installation. The install files will be automatically extracted and the wizard will guide you through the installation process.

MESSAGE: This installation package is intended for 32-bit operating systems. Please use an installation package for 64-bit operating systems.
