When you type www.google.com , your PC checks its hosts file before asking the internet’s DNS servers.

This technical guide explains how the Windows Hosts file affects SolidWorks, why it blocks installations, and how to safely reset it to restore full functionality. Understanding the Hosts File and SolidWorks Activation
Modern versions of SOLIDWORKS (including 2024, 2025, and 2026) frequently attempt to reach out to Dassault Systèmes' activation and license validation servers. During a "cracked" or "offline" activation process, this validation needs to be prevented. If the software reaches the internet and fails to validate a serial number, it may revert to a trial mode, display "License Error -15,10,10061", or simply refuse to launch. Blocking via the hosts file ensures that while you maintain internet connectivity for other applications, SOLIDWORKS cannot check its license status externally.
