Just build yourself a .txt file on your desktop and write the above mentioned string into it (replace <your windows username> with your username!):
Code:
java -jar C:\Users\<your windows username>\AppData\Local\Minion\app\Minion-jfx.jar
Aftwerwards save the file and rename it from .txt to .bat
You are able to right click this batch .bat file and choose the properties. Assign a symbol for it, like the one from the Minion .exe file.
you are able to double click this .bat file then to start Minion.
