I'm trying to follow this tutorial :
I am not exactly sure if I am following the steps correct but I get an error when I write the command in the terminal CustomGenesis.json --datadir
The error is:
This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel.
Does anyone can help me solve this error and explain me what it is?
