Almost all of the python files should live in their respective folders (<code>C:\Python26</code> and <code>C:\Python27</code>). Some installers (ActiveState) will also associate <code>.py*</code> files and add the python path to <code>%PATH%</code> with an install if you tick the "use this as the default installation" box.

Windows 7 64-bit, with both Python3.4 and Python2.7 installed at some point :)

I'm using Py.exe to route to Py2 or Py3 depending on the script's needs - but I previously improperly uninstalled Python27 before.

Py27 was removed manually from C:\python\Python27 (the folder Python27 was deleted by me previously)

Upon re-installing Python27, it gave the above error you specify. 
It would always back out while trying to 'remove shortcuts' during the installation process.

I placed a copy of Python27 back in that original folder, at C:\Python\Python27, and re-ran the same failing Python27 installer. It was happy locating those items and removing them, and proceeded with the install.

This is not the answer that addresses registry key issues (others mention that) but it is somewhat of a workaround if you know of previous installations that were improperly removed.

You could have some insight to this by opening "regedit" and searching for "Python27" - a registry key appeared in my command-shell Cache pointing at c:\python\python27\ (which had been removed and was not present when searching in the registry upon finding it).

That may help point to previously improperly removed installations.

Good luck!

I know it is an old question, but I ran into this problem with 2.7 and 3.5. Though 2.7 would not show up in my default windows uninstall list, it showed up fine in the ccleaner tools tab under uninstall. Uninstalled and reinstalled afterwards and it has been smooth coding ever since.

I also removed the remaining python associated directory &amp; files from the c: drive and also from “my documents” folder, since I created some files there.

It's actually quite simple.
When you installed it, you must have done it using some .exe file (I am assuming). Just run that .exe again, and then there will be options to modify Python. Just select the "Complete Uninstall" option, and the EXE will completely wipe out python for you.

Also, you might have to checkbox the "Remove Python from PATH". By default it is selected, but you may as well check it to be sure :)

If you still have the python installer on your PC, you can double-click on it (run it, it will open the installer window), and select the &quot;Uninstall&quot; option. It will uninstall that python version (if the installer is for Python3.9, then Python3.9 will be uninstalled, if it is for Python3.10, then that version...)

I installed both Python 2.7 and Python 2.6.5. I don't know what went wrong, but nothing related to Python seems to work any more. e.g. "setup.py install" for certain packages don't recognize the "install" parameter and other odd phenomena...

I would like to completely remove Python from my system. 
I tried running the 2.7 and 2.6 msi files and choosing remove Python and then running only 2.6 and reinstalling it. Still stuff don't work.
