1. Hosts File Intervention
When installing SolidWorks in a professional environment, the client machine must often communicate with a license or PDM server. If your local network's DNS cannot resolve the server's name to its IP address, the installation or software launch may fail.
During the installation of SOLIDWORKS, the software requires access to specific servers to verify the license, activate the product, and download necessary files. The host file plays a vital role in this process by directing the installation wizard to the correct servers. However, if the host file is misconfigured or contains incorrect entries, it can block the installation process, resulting in a "SOLIDWORKS host file block install" error.
