I'm using the pywin32-216.win32-py2.6.exe package to install pywin32 on Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on win32. I am seeing the following post install errors. Could someone help me understand what going wrong? Thanks in advance.

Most probably pywin32 requires administrator privileges to be installed successfully. I am not sure how to do that on WinXP, but Microsoft has a page about it.
I managed to fix the problem by eventually cleaning all traces of Python 2.6 from my system and re-installing it + pywin32. It was eventually as simple as just double clicking the setup files.
Another answer for the googlers:
I has the same issue, it turns out it originated because I have installed python in the past, removed it and reinstalled it to another location.
In order to solve it I had to:
Remove old installations (Uninstall + manually from registry) - as Danish advised (both in main root and in Wow6432Node).
In the registry update the location of current location of the python folder path (in InstallPath and PythonPath).

Although I have been using Python for a while, I am relatively new to Anaconda, and package handling in general seems to cause a lot of problems for me.
I am trying to get xgboost up and running with Anaconda. I eventually managed to install it by using the command:
conda install -c anaconda py-xgboost
in the Anaconda prompt.
When I now try import xgboost in the PyCharm Python Console, I am given the following error:

I have searched for similar questions on StackOverflow, but I've had no luck, besides finding complicated answers which I did not feel comfortable implementing without fully understanding, and which I am not sure are applicable to my scenario anyway.
Some further things to note, which may be related:
Originally, I installed the package using pip install xgboost in the Pycharm Terminal before realising my mistake.
When I initially tried testing the xgboost package, I did so (stupidly) in a file named xgboost.py. I have since deleted this project. I uninstalled and reinstalled xgboost afterwards.
I have tried several things to try and resolve this issue which may have complicated things further. For example, I deleted the 'xgboost' folder from inside 'C:\Users\Richard\Anaconda2' when typing conda uninstall xgboost into the Anaconda prompt failed.
Would anyone be able to shed any light on what is causing this issue? This is my first question on stack overflow, so I apologise if my question has not been posed completely correctly with regards to the guidelines.
After further searching, I managed to answer my own question.
The xgboost (C++) library must be compiled and built before it can be used as a Python module. To do so, I carefully followed the instructions on this page:
https://www.ibm.com/developerworks/community/blogs/jfp/entry/Installing_XGBoost_For_Anaconda_on_Windows?lang=en
and now, I think, xgboost is working fine. This is the first time I have encountered a package where this was required, hence the confusion. Hopefully this will help someone else who has the same issue.
I am tyying to install anaconda on my mac but at the last step of installtion it gives me following error:

Any idea how i can get ahead from here?
Thanks!
Just update python to the next version and try installing Anaconda again.
I had python 2.7 and then I updated it to python 3 and I was able to install Anaconda graphical installer successfully.
I have Windows 8 64 bit and Python 2.11 64 bit. I install VTK library using pip command. It shows the following error while running:
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>

My PATH are:
C:\Python27\Lib;
C:\Python27\Lib\site-packages;
C:\Python27\Lib\site-packages\vtk;
C:\Python27\Scripts;
Thanks for your help.
I could solve the problem with uninstalling .vtk 5 and installing vtk 6.2. 0 from http://www.lfd.uci.edu/~gohlke/pythonlibs/. I also install PyQt4
In my case, the problem was resolved by adding PyQt4's directory to PATH, as suggested here. That is, the directory similar to
C:\Python27\Lib\site-packages\PyQt4
which contains the DLL that it's looking for.
We've installed the python-ldap(2.4.19) module without errors and perform most of the operations successfully. However ldap.set_option always returns a exception when we try to load certificates to use ssl (ldaps).
It occurs on notebooks running Yosemite but not on Mavericks or Linux. (All Macbooks have xcode installed)
We think it should be some missing/outdated/updated lib but we don't know how to find it.
Any clues?

got around this by installing openldap threw brew, and then manually downloading the tarball, and mod setup.cfg to pick up /usr/local, and then install.
http://sourceforge.net/p/python-ldap/bugs/65/ is the ticket to add /usr/local to the defaults on python-ldap.
I can't install a library, or at least numpy. I have a Windows 7 Home Premium 64 bits and Python 3.3.3 (v3.3.3:c3896275c0f6, Nov 18 2013, 21:18:40) [MSC v.1600 32 bit (Intel)] on win32.
I go to their website to Getting Numpy which sends me to SourceForge where I download the latest (I have already update my python to 3.3) and open and install it. Apparently successfully. But when I open python and type import numpy I get:
Traceback (most recent call last):

The last line it means that %1 it is not a valid Win32 program.
Tere is a similar question here where they point the OP to the Windows Installer. So I download the zip file and decompress it. And now?
Somewhere I found that it should be in the Lib folder and then run the setup.py file. I tried again to import numpy but again the same error.
I found here some instructions, but the first step it is already different, my error message it is not the same, is the same as step 6. But then the step 8 is to install the 32-bits system after uninstalling numpyand Python, but there is no 32 version for Python 3.3 (or at least not that I understand). What should I do?
So I reinstall the python 3.3 I already had.
And this time when I type from numpy import * or import numpy I don't get an error but when I try to make an array I do:
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
type(array([1,6,3,7]))
NameError: name 'array' is not defined
Another way I found is from this source with python 3.3 which leads me to another unofficial page where I download the numpy-MKL-1.8.0.win32-py3.3 file following the steps of the blog. But still the same error of NameError.
I didn't restart the computer yet...
I forgot something else or I miss one step?
So, after rebooting it seems to work well. I post here what worked for me
Install python for just for me. Download from here the library, install the latest (or the version you want) with 32 bites even if the computer is 64 bites and restart the computer.
Christophe Gohlke maitains an extensive collection of windows binaries for various python libraries including numpy. Have you tried here?
