pip install intelhex

You are using pip version 6.1.0, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Requirement already satisfied (use --upgrade to upgrade): intelhex in c:\python27\lib\site-packages

Hi John, 
Could you try to update python to at least v3.5.1  ? I'm using Python v3.7 and it works fine for me. 
Also please make sure you installed pip3 install -r requirements.txt 

Also, please use the correct .json file. I attached here for reference.

Hi John,

A "," is missing after application_version":1 . Your .json file should look like: 

{
    "bootloader_config": {
        "bootloader_id": 1,
        "bootloader_version": 1,
        "company_id": 89,
        "application_id": 1,
        "application_version": 1,
		 "public_key": "558cdba44e90f9354a6eae8436ff8a8161556b4bea6980baa9890a6536fe248e5f6a333c1dffa27fc529c67609a1345888176a77a969a700e442271ea792d847"
    }
}
