Error "filename.whl is not a supported wheel on this platform"

I would like to install scipy-0.15.1-cp33-none-win_amd64.whl that I have saved to the local drive. I am using:

pip 6.0.8 from C:\Python27\Lib\site-packages
python 2.7.9 (default, Dec 10 2014, 12:28:03) [MSC v.1500 64 bit (AMD64)]

When I run:

pip install scipy-0.15.1-cp33-none-win_amd64.whl

I get the following error:

scipy-0.15.1-cp33-none-win_amd64.whl is not a supported wheel on this platform

What is the problem?
