I am using intl-tel-input to create a control to display mobile numbers. because the flags are realy small, I need to have them bigger.

As they describe here: https://codepen.io/jackocnr/full/ONXWgQ

I should run grunt img and grunt css to do this. however the grunt img command fails and I get this error

 C:\Users\myname\AppData\Roaming\npm\node_modules\evenizer\lib\evenizer.js:43
         throw err;
         ^

 Error: Command failed:
     at ChildProcess.<anonymous> (C:\Users\myname\AppData\Roaming\npm\node_modules\evenizer\node_modules\imagemagick\imagemagick.js:88:15)
     at ChildProcess.emit (events.js:400:28)

   timedOut: false,
   killed: true,
   code: null,
   signal: 'SIGKILL'
 }

I have

• installed ImageMagick,
• ran the commands as administrator
• ran npm install evenizer -g

I am probbably forgetting something silly, but I do not know what.
