Hi, I was doing a fresh installation for Python 2.7.9 (32 bit) and 3.4.3 (32 bit) (downloaded from PSF) on Win7 X64 today, and I found that there is no 'Script' folder in 'Python27' and 'Python34' folder as first child level folder, but there is one in Tools. However, I couldn't find pip within that 'Script' folder, although pip should be installed with Python by default. The other I was doing the same installation for my other PC and laptop, there was 'Script' folder (as first level child folder in 'Python27' and 'Python34') containing pip. So what is going on? how to install pip and maybe other useful scripts this way? 

'C:\Pythonxy\Lib\site-packages' contains nothing but a README file. I tried 'python -m ensurepip' in 'C:\Python34'. I got the following errors:

I have also tried out 64bit Python installation, but got the same result. So how to fix this? I posted the same message on comp.lang.python and Python Google group with no response so I guess i may try some luck here.

cheers

This is a duplicate of issue22028. 

Daiyue Weng: to move forward, can you apply the fix referred to in this post:

https://mail.python.org/pipermail/python-list/2015-January/696688.html

(ie the "removing corrupted keys" section from http://www.swarley.me.uk/blog/2014/04/23/python-pip-and-windows-registry-corruption/).

Steve: if you can, please commit your change from issue22028; I just don't have the time at the moment to run up a clone and test it, but it looks safe to me.

The fix that referred to another thread solved my issue completely.

thanks
