virtualenv problem

[D. Xenakis]

Hi there.
Im using windows 7 64bit
I have installed python 3.3.2 in C:\Python33
and then easy_install , pip, and virtualenv.
But i do not know if the virtualenv installation is correct as i cant seem to be able to create any virtual enviroment yet.

How can i check if everything is correct? What exactly should i do to create a virtual enviroment into my new_project folder located here: in C:\new_project ?
I think there is something wrong with the installation because when i run through idle the virtual-env scripts located in "C:\Python33\Scripts" then i get the following..

Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:06:53) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.

You must provide a DEST_DIR
Usage: virtualenv-3.3-script.py [OPTIONS] DEST_DIR

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -v, --verbose         Increase verbosity
  -q, --quiet           Decrease verbosity
  -p PYTHON_EXE, --python=PYTHON_EXE
                        The Python interpreter to use, e.g.,
                        --python=python2.5 will use the python2.5 interpreter
                        to create the new environment.  The default is the
                        interpreter that virtualenv was installed with
                        (C:\Python33\pythonw.exe)
  --clear               Clear out the non-root install and start from scratch
  --no-site-packages    Don't give access to the global site-packages dir to
                        the virtual environment (default)
  --system-site-packages
                        Give access to the global site-packages dir to the
                        virtual environment
  --always-copy         Always copy files rather than symlinking
  --unzip-setuptools    Unzip Setuptools when installing it
  --relocatable         Make an EXISTING virtualenv environment relocatable.
                        This fixes up scripts and makes all .pth files
                        relative
  --no-setuptools       Do not install setuptools (or pip) in the new
                        virtualenv.
  --no-pip              Do not install pip in the new virtualenv.
  --extra-search-dir=SEARCH_DIRS
                        Directory to look for setuptools/pip distributions in.
                        You can add any number of additional --extra-search-
                        dir paths.
  --never-download      Never download anything from the network. This is now
                        always the case. The option is only retained for
                        backward compatibility, and does nothing. Virtualenv
                        will fail if local distributions of setuptools/pip are
                        not present.
  --prompt=PROMPT       Provides an alternative prompt prefix for this
                        environment
  --setuptools          Backward compatibility. Does nothing.
  --distribute          Backward compatibility. Does nothing.
