Now you have to modify the "Path" environment variable using Powershell running

    [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")

Download and install the last version of Distribute for Windows from http://python-distribute.org/distribute_setup.py

At this point you can install pip using easy_install

    easy_install pip

Now install `numpy <http://www.numpy.org>`_ library using *easy_install* because installation from pip is broken (this is required only for version >= 0.7.1)

    easy_install numpy

Finally install pyModis using pip

    pip install pyModis
