python34 instalando o rtree no Windows 64

Question

Estou usando o windows10 64 bits, meu os.name é 'nt', usei o pip para instalar, mas está reclamando sobre o spatialindex_c.dll

File "C:\Users\Bachir\AppData\Local\Temp\pip-build-td64lrth\rtree\rtree\core.py", line 101, in <module> raise OSError("could not find or load spatialindex_c.dll") 
OSError: could not find or load spatialindex_c.dll

Eu baixei o rtree-0.8.2 e depois executei o python setup.py install e eu tenho a mesma mensagem

PS C:\Users\Bachir\documents\Python Scripts\Rtree-0.8.2> python setup.py install
Traceback (most recent call last):
  File "setup.py", line 4, in <module>

Eu não carreguei os arquivos dll do spatialindex 'libspatialindex-1.8.1-win-msvc-2010-x64-x32.zip'. este arquivo contém 32 e 64 bits, descompacte e coloque na pasta de instalação, ao instalar usando o python setuo.py instale ele ainda reclamando sobre o arquivo dll spatialindex
