Troubleshooting activation errors

Right-click the Command Prompt icon and select Run as administrator.
Type the command netsh winsock reset and press the Enter key. Restart your computer and attempt to activate your ESET product.

Errors can occur when the system time on your machine is set incorrectly. Set your system clock properly to resolve this error.
Navigate to C:\Windows\System32\drivers\etc and verify if the hosts file contains any DNS poisoned entries related to the edf.eset.com domain.

If any DNS poisoned entries are found, remove these entries from the hosts file using a text editor like Notepad or Notepad++. This action requires Windows administration privileges.
