I'm a beginner in python's framework 'flask', i was following this [link](http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world) for the installation and demo App(to create virtual environment).

I'm using python 3.3.2 and on windows platform

```
 python virtualenv.py flask

```

the above command gets well executed and all the files are downloaded correctly but when i execute 

```
 pip install flask==0.9

```

it gives me the following error

```
