Toolbox closing

Enonic version: 6.9.3
OS: Windows 10

When i try to start toolbox.bat it just closing. I am doing something wrong?

What commands are you sending into it? It is not meant to be used without any of the different commands listed here:

Sounds to me that you try to run it by double-clicking it through the Windows Explorer. Am I right? (At least the same happened to me once or twice before I read the documentation)

You need to call the toolbox.bat from the command line instead.
