Problem about copy Engine to New Computer

Hello, my English is very poor, I hope you can read these words of Machine Translation
I am a university teacher who mainly teaches games and fine arts. I need to install UE4 on some computers in my classroom that are not networked. For this reason, I copied the engine from my computer to classroom computer. Do not install by Epic Games Launcher. But that would cause my project to not be recognized by my computer and classroom computer at the same time. I asked a lot of people, and they said I must to switch engine version at the classroom computer. But I can’t find any specific steps in your website and help documentation. Can you give me some answers?

Take a source version and build on each computer.

You need to link your account to github, install VS and build.
