IV. Unable to reinstall 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 ESET product for Windows after uninstalling an earlier version and are experiencing performance issues, it is likely that the previous version was not completely uninstalled.
Follow the steps below to diagnose and fix your failed reinstallation:
-
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.
-
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.
