III. Reinstall

Have your ESET Activation Key available

After uninstalling and reinstalling your product, you must type or copy/paste your Activation Key to complete the activation and restore protection.

  1. Navigate to the saved install file (see section I). Double-click the file to open ESET Live Installer.

  2. Follow the on-screen instructions to install and activate your ESET Windows home and small office product.


IV. Unable to reinstall my ESET product for Windows 

Failed reinstallations are often caused by a partial or unsuccessful uninstall of a previous ESET security product. If you have attempted to reinstall your Windows ESET product after uninstalling an earlier version and are experiencing performance issues, it is likely that your previous version failed to uninstall. Follow the steps below to diagnose and fix your failed reinstallation:

  1.  Remove all non-ESET antivirus software and reinstall your product. Reinstallation issues can be caused by another company's antivirus software conflicting with your ESET security product.
     
  2. If your reinstallation still fails, run the ESET Uninstaller and reinstall your product. The ESET Uninstaller deletes all files, folders, registry entries and program drivers that can be left behind during a failed installation and can interfere with reinstallation.
