Hi,
What you can try to do:
1. copy the path to the directory where you have the bot.
example your path (from screenshot):
c:\users\machine\desktop\discord-rustserverstatus-master(1)\discord-rustserverstatus-master
2. open Command prompt.
example: keyboard shortcut: win+r (run) and then type: cmd
You can also try to open cmd as administrator if you get any trouble with permissions.
3. in command prompt:
cd c:\users\machine\desktop\discord-rustserverstatus-master(1)\discord-rustserverstatus-master
If this is your path where you have extracted the files.
4. run command in command prompt:
npm install
This is install all the dependecies you need to be able to run the application.
5. To start the nodejs application in command prompt:
node app.js
You start the nodejs server trough cmd or powershell.
It will not work if you try to dobbel click on app.js or clicking on the node.exe shell.
