| Issue | Possible Cause & Solution | |------|---------------------------| | | Cause : The custom server path is incorrect. Solution : Double‑check the path. For folder‑based updates, use the correct format: file:///C:/Path/To/Folder . For network shares, use \\Server\Share\Folder . Ensure the user account has read permissions. | | "Modules update failed" | Cause : This can result from an invalid or expired license , or an authentication problem with the update server if one is required. Solution : Verify that your license is still valid and that the offline license file (.lf) you are using with the Mirror Tool is current and correctly configured. | | Mirror Tool fails with Visual C++ errors | Cause : Missing or incorrect Visual C++ Redistributables. Solution : Install Visual C++ Redistributable for Visual Studio 2010 and the x86 version of Visual C++ 2015 Redistributable . Even on a 64‑bit system, the x86 version is required. | | Mirror downloads are huge or taking forever | Cause : By default, the Mirror Tool may download updates for all supported products and versions, resulting in a very large mirror. Solution : Use advanced filtering parameters to limit the download to only what you need. For example, --filterFilePath (to specify a JSON filter) and --dryRun (to test without downloading) can drastically reduce the download size. | | Offline updates do not offer the latest version | Cause : This was a known bug in some older versions of ESET Smart Security Premium. Solution : Ensure you are running the latest version of the software (e.g., 19.0.11.0 or newer), as this issue has been fixed. | | Product End of Life warnings | Cause : You are using the discontinued "ESET Smart Security" instead of the supported "ESET Smart Security Premium". Solution : Upgrade to ESET Internet Security or ESET Smart Security Premium , as the older product will no longer receive updates. |
