i read on the setuptools page that they do not have setup for win 64 bit and instead their is ez_setup.py which i downloaded and from command prompt typed python ez_setup.py then i checked back in the D:\Python26\Lib\site-packages directory their is a new easy-install.pth,setuptools.pth,setuptools-0.6c11-py2.6.egg,andd setuptools-0.6c12dev_r88846-py2.6.egg file, now from python interpreter i can import easy_install but when i try to run easy_install from command prompt to install any p[ackage say ipython i get error message saying

'easy_install' is not recognized as an internal or external command,
operable program or batch file.

now what should i do to make easy_install workingon win 7 x64 ?

so figured out sometimes even having c:\python2.6\libs to environment paths is not enough so I had to add C:\Python26\Scripts and it worked like charm
