Flask, IIS, Python, wfastcgi Error occurred while reading WSGI handler: ImportError: cannot import name 'Flask'

My problem is that I'm trying to deploy a simple flask app.py :

from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
    return "Hello from FastCGI via IIS!"
if __name__ == "__main__":
    app.run()

with that web.config:

<?xml version="1.0" encoding="utf-8"?>
     <configuration>
     <system.webServer>
       <handlers>
        <add name="Python FastCGI" path="*" verb="*" 
        modules="FastCgiModule" scriptProcessor="C:\Python34\python.exe|C:\Python34\lib\site-packages\wfastcgi.py" 
    resourceType="Unspecified" requireAccess="Script" />
       </handlers>
        <httpErrors errorMode="Detailed" />
     </system.webServer>
     <appSettings>
       <!-- Required settings -->
       <add key="WSGI_HANDLER" value="app.app" />
       <add key="PYTHONPATH" value="D:\Web\flaskapp" />
    </appSettings>
</configuration>

i get the errorError:
