Troubleshooting checklist for "Module update failed"

1. If you are not using the latest version of your ESET application, upgrade it.

2. Verify the hard drive volume (partition) where your ESET application is installed (for example, C:\) has enough free space (at least 1 GB).

3. Verify that your subscription is valid (not expired).

4. Clear the update cache.

5. Remove any previously installed antivirus software.

6. If you use a third-party firewall software, exclude ESET from detection. If you only use ESET firewall, skip this step.

7. Disable receiving updates through a proxy:

   Locked update settings

   If your device is managed by ESET PROTECT or ESET PROTECT On‑Prem, your administrator may enforce your ESET application to use ESET Bridge for downloading updates. When ESET Bridge is enforced, your update settings become locked (read‑only).

   In this case, your administrator can disable ESET Bridge when the modules update fails from the ESET PROTECT Web Console.

   If you are no longer a managed user, uninstall the ESET Management Agent to remove the enforced settings and then uninstall and reinstall your ESET endpoint application.

   1. Open the main program window of your ESET Windows application.

   2. Press F5 to open Advanced setup.

   3. Click Updates, expand Profiles → Updates.

      

   4. Expand Connection options and select Do not use proxy server from the Proxy mode drop-down menu. Click OK.

      

8. Test the reachability of the ESET update server:

   1. Click Start and type cmd. Right-click Command Prompt and click Run as administrator.

      

   2. In Command Prompt, type ping update.eset.com and press Enter.

      

   3. Check the output. If you can reach the update server, you will see a Reply from message followed by the IP address of the server you are trying to reach.

      

9. Uninstall and reinstall your ESET application.

   • Home and small office users
   • Business users:
     • Non-managed users (uninstallation, reinstallation)
     • Managed users
       
       

10. Clean your computer of a virus or malware.
