Deploying Python web app (Flask) in IIS using FastCGI get 500 Internal Server Error

I am trying to deploy Flask app in IIS.

But I get the 500 FastCGI error.

error code:"0x8007010b"

Here are the steps I've taken:

OS:windows10

Python version:3.6.5

1.install url rewrite2.0

2.pip install wfastcgi

3.Enable wfastcgi

4.create HelloAPI.py

5.create web.config

HelloAPI.py

from flask import Flask
app=Flask(__name__)

@app.route('/',methods=['GET'])
def index():
    return "Hello Flask!"

if __name__=='__main__':
    app.run(debug=True)

web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="FlaskFastCGI" path="*" verb="*" modules="FastCgiModule" scriptProcessor="d:\users\hhhung1\appdata\local\programs\python\python36-32\python.exe|d:\users\hhhung1\appdata\local\programs\python\python36-32\lib\site-packages\wfastcgi.py" resourceType="Unspecified" requireAccess="Script" />
    </handlers>
    <security> 
        <requestFiltering allowDoubleEscaping="true"></requestFiltering> 
    </security> 
  </system.webServer>

  <appSettings>
    <!-- Required settings -->
    <add key="WSGI_HANDLER" value="HelloAPI.app" />
    <add key="PYTHONPATH" value="~/" />
  </appSettings>
</configuration>

Is there something I miss?

Problem solved. I grant the r/w right to python.exe folder and it works fine now.
