I have a rcf file, but can't use sonicwall VPN, how else might I connect?

(I freelance)
I have a potential client that wants to show me their product, and to do so they want me to connect with a sonicwall VPN. I have the rcf file but I can’t get the VPN client to work on my pc for multiple reasons. (No troubleshooting help needed, it is beyond my control). Is there an alternative way I can connect to their machine? Is connecting via another VPN client possible? Or can I hardcode some data into my machine that will work?

Thanks!

Ask them if they use the SSLVPN option. If you have restrictions on what can be installed on your device, you may have another issue.
