No license available looks like you installed the wrong BimS, you will use Basic not BimCloud. Both computers should have AC installed with BimS installed inn one of them.
Then you need to configure it, make sure that both are within the same wifi network (configuring this is the hardest part) so that you can assign an IP address to the computer that will be running the BimS.
I also have found out that it is easier to set this up if you have your own router to create a local network instead of using your local school's network.
If you want to work remotely then that is another issue since you will need a static IP address and configure a VPN.
