On Windows, when you repair your Python 3.4 installation, it
will not reinstall pip & setuptools. Here by 'repair' I mean
a 'Windows Installer' based repair installation.

Reproduced using:

• Windows 7 SP1 x64.
• Python 3.4.0 (32-bit).

To reproduce do the following:

• Install Python.
  • For example to the target installation folder:
    'C:\Program Files (x32)\Python\Python340'.
  • This will automatically install pip & setuptools
    Python packages.
• Delete or rename your target installation folder.
• Rerun your Python installation and choose to repair
  the current installation.
  • This will restore the original target installation
    folder and all the basic installation files under
    that folder, but it will not reinstall pip &
    setuptols Python packages.

There is currently a condition in the installer to run ensurepip only if this is an installation (i.e. not an uninstallation); this should probably be extended to also run this on repair.

Contributions are welcome.

On Windows 7 SP1 x64 after having installed Python 3.3 (x64) in “c:\Python33” and then subsequently installing Python 3.4 (x64) in “c:\Python34”, and then uninstalling the Python 3.3 (x64) and I’m not sure what else I may have done, I can no longer do any of the following:
Open an IDLE window using the Windows Start Menu;
Uninstall, Change, or Repair Python 3.4 using Windows Programs and Features;
Uninstall Python 3.4 using Windows Start Menu;
Reinstall Python 3.4 using the current 3.4 .msi install program.

I would like to go back to being able to do a forced fresh install.

I am a Python newby so maybe I should open a new incident but I don’t know how to start one yet.

Perhaps I should try the previously described reproduce procedure by doing the following:
Rename or delete target installation folder and then rerun Python installation procedure to install.

Martin: Thank you for your prompt and helpful response to my attempt to tag
along to a possibly similar bug. I had been working on my issue for about
two weeks and truly believed it was a bug before i adventured as I did. As
you know, the difference between a problem and a bug is who comes up with
the fix.

I continued working my issue and discovered I could reinstall by running
msiexec with the "/l *v" option and again with the "/fa /l*v" option which
forces all file files to be reinstalled. I still consider this to be a bug
in the Python installer because the installer does not truly repair. But I
am a happy camper now will use the python-list you recommended.

The installer system for v3.4 and before has long since been retired.
