You don't need to ask 5 times the same question.
What you see isn't an error. You see this because you didn't pay for the licenses of some of the IP that you are using, As I said, this doesn't prevent the system from running and you from doing your tests.
Once the system is compiled into a sof file, you can upload it as many times as you want and when you want to your FPGA. All you need is the Quartus programmer software, and you can use it without any Internet connection.
