[PyMOL] Problem with pymol installation

Hi everybody,
I recently restored my laptop to factory settings and I am trying now to
install latest precompiled pymol version  following the instructions from
http://www.pymolwiki.org/index.php/Windows_Install.
I have installed python 2.7.11 and put in a Pymol_installation folder pip
8.0.3, numpy 1.10.4+mkl, pmw 2.0.1, pymol 1.8.1.0 and pymol_launcher 1.0
whl files, all of them downloaded from the  Christoph Gohlke webpage.
However, after typing in the command prompt

C:\Python27\python.exe pip-8.0.3-py2.py3-none-any.whl/pip install
--no-index --find-links="%CD%" pymol_launcher

I get the following error:

 "Could not find  a version that satifisfies the requirement pymol-launcher
(from versions: )
No matching distribution found for pymol launcher"


Could you provide me any help? Am i doing anything wrong? Have i skipped
any step in the installation process?

Thanks

Sergio
