I’m confused are you trying to install Windchill on the laptop? Or are you trying to connect to an existing Windchill server?
I’ve installed Windchill on a laptop before, I don’t think you really want to do that unless your just trying to figure out the software.
If all your trying to do is connect, you need to register your server.
File, Manage Session, Server Management, Server, Register New Server, and enter the Name, and web address. Then log in and select a workspace. Pick the server, then select Server, Set as Primary Server, Close. You should be all set.
