Using a hosts file to circumvent license validation is a . The EULA strictly forbids any attempt to bypass or tamper with the software's license management and validation mechanisms.

Network administrators and users implement host file blocks for SolidWorks for several distinct engineering and IT infrastructure reasons. 1. Disabling Telemetry and Background Data Collection
By default, Notepad only displays .txt files. In the bottom right corner of the Open dialog box, change the dropdown menu from to All Files ( . ) . Solidworks Host File Block
Even after uninstalling, SolidWorks leaves background services (like SolidWorks Licensing Service ). These services attempt to send telemetry. The hosts file stops these background processes.
The potential cost of this "free" solution is your company's legal safety and financial health. Invest your time in understanding and correctly using the powerful, legitimate tools that SolidWorks already provides for license, update, and data management.

SOLIDWORKS, a leading 3D CAD software, requires a stable license activation process and, in some cases, network connectivity for PDM (Product Data Management) systems. Sometimes, users encounter issues where SOLIDWORKS fails to activate, cannot connect to the license server, or displays errors related to network connectivity. A common, yet often overlooked, cause for these issues is a .
: SolidWorks instantly failed to find the old server on the loopback, gave up on the "bad" local info, and finally looked at the DNS settings to find the new server. Why do users do this?
Shift from standalone serial numbers to a SolidWorks Network License (SNL) manager deployed on a secure, internal server. This minimizes how often individual workstations need to reach out directly to the public internet for individual validation. What are you using (Standalone

| Goal | Tool | Hosts File Alternative? | | :--- | :--- | :--- | | Block telemetry | Windows Firewall (Outbound Rules) | No (Firewall is safer) | | Prevent auto-updates | Group Policy Editor (gpedit.msc) | Yes, but risky | | Use offline license | Request an Offline Activation file from Dassault | Never use hosts file | | Isolate software | Run in a Windows Sandbox or VM | Better isolation |
The software displays warning messages indicating that it cannot reach the activation server, warning that you have a limited number of days remaining before the software disables itself.
