installation - Unable to install Python on Windows 8

Recently I decided to upgrade from Python 2.7 to Python 3.4 on my Windows 8 laptop. So I uninstalled Py2.7, downloaded the .msi file from python's site and ran it. I found that every installer I tried for both 3.4.1 and 3.4.0 would give me an error saying that part of the installer didn't work. The exact error message is "There is a problem with this Windows Installer package. A Program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." I've never had this kind of problem before and certainly not with Python. Does anyone know of a good way to try and debug this? It's persisting across so many installers that I'm sure it has to be something on my system.

EDIT: Thanks for the tip about the log file. It's very large (larger than I'm allowed to post on this site ~320k characters). Here's the bit right after it says 'fatal error'. This is from running the suggested code on the installer for 3.4.1 64 bit.

I don't have a concrete answer here, but here's a few rather generic MSI debugging steps that can narrow down the issue:

First, we need to generate a log of the installation. The command msiexec /i installer.msi /l*v log.txt can do that.

Once you have the log, it's the first thing you can do is search for Error or FatalError (as you did do). Note that this occurs in the log after the rollback actions, so you'll need to scroll back up past many pages of FileRemove, ComponentUnregister, etc.. In fact, you might find searching for InstallFinalize and looking directly above that to be more useful (ignore the first occurrence near the top).

Here are the interesting lines from your error log:

Contact your support personnel or package vendor.  Action UpdatePip, location: C:\Python34\python.exe, command: -m ensurepip -U --default-pip 

This is an interesting error, and I am not entirely sure why python -m ensurepip -U --default-pip would be failing. I would suggest perhaps trying to grab a portable copy or compiling from source and then running the command manually, to see if you can get more information. Failing that, you might try contacting the maintainers via IRC, a mailing list or some other method.

And, of course, if you do figure out why please post a self-answer here to help others!

Hooray, Finally after lats of investigation I find the solution, Go to the system path and remove any path address which point to python27 or any other version and run the msi installer.
