Ngrok doesn't work. Does anyone know why?

I have a small problem!
I installed ngrok to play with friends on my Minecraft server.
The problem is this: I download ngrok, unzip the folder and run the .exe file as an administrator. However, there's only a short command line that closes again immediately. Why is that?

Ngrok is a command line tool and must be executed from the command line with appropriate arguments. There's nothing with a double click since Ngrok has no GUI.

So open the command line, go to the folder where the Ngrok * .exe is located and run ngrok from the command line with the appropriate arguments for the desired application. You can find out which arguments these are in the https://ngrok.com/docs.

Ngrok must of course be run via a CMD since it has no gui. I prefer to recommend Hamachi

I actually like hamachi too, but I don't want my friends to have to install a program
