To safely upgrade to Windows 7, please follow the steps below to download the latest ESET product installer, uninstall your current ESET product, upgrade your Microsoft operating system from Windows Vista to Windows 7 and then reinstall your ESET product.

ESET NOD32 Antivirus users

ESET NOD32 Antivirus users can upgrade to Windows 7 without uninstalling their software. We recommend temporarily disabling your antivirus software before you begin the upgrade process. If you have ESET Smart Security, follow the steps below to continue with the upgrade process.

  1. Download the latest version of ESET Smart Security before you uninstall your current version so you will not have to browse the Internet without Personal firewall protection. Save the installer to your Desktop:

    ESET Smart Security

    Do not attempt to run the installer yet

    If you are prompted to click Run, instead choose Cancel. You'll need to do the installation after your upgrade to Windows 7 is complete.

  2. When your installer file finishes downloading, uninstall ESET Smart Security by clicking Start All Programs ESET Uninstall. After you uninstall, you will need to restart your computer.
  3. After restarting, confirm that you can see hidden files and folders by  clicking Start Control Panel Appearance and Personalizations Show hidden files and folders under Folder Options and select the Show hidden files and folders option.
  4. Click Start My Computer. Navigate to and delete the following folders:

    C:\Program Files\ESET

    If the above folders are not found, proceed to step 5.
  5. Upgrade your operating system from Windows Vista to Windows 7 by following the instructions provided by Microsoft:
  6. After you have successfully upgraded from Windows Vista to Windows 7 and have restarted your computer, navigate to your saved installer on the Desktop and double-click it to open.
