To enable me to continue working if the internet is down
I'm assuming that you are SNL (SolidWorks Network License). If so, then you can check-out a license (using the SolidNetWork License Manager Client tool - in your SW20XX-tools app. folder) , or if you have VPN into the server that is supplying the license you can connect via VPN.
Of course, to use the SW Network tool you need to be connected to the server (at work) or via VPN.
Mark is correct. It's the only way. If you were allowed to take completely offline, it would be free on social media.
