I installed Python 3.4.3 over 3.4.2 on Windows 7 ... and now I can not remove Python

I installed Python 3.4.3 over 3.4.2 on Windows 7 and got problems running IDLE.

When I use the Windows uninstaller through the control panel, I get the message:

"There is a problem with this Windows Installer package, the program required to complete this installation cannot be started. Contact your support staff or package provider."

If I try to remove Python through the msi file, I get the same message.

There is no Python34 directory on my computer. I noticed that there is a registry entry HKEY_LOCAL_MACHINE \ SOFTWARE \ Python \ PythonCore \ 3.4 \ Modules. I did not want to contact my registry, but can I safely delete this entry? Delete more?

I used MicrosoftFixit.ProgramInstallUninstall, and I was able to uninstall Python34, and then it was reinstalled without problems.

There was a similar problem. This is what I did:

Reboot the computer (kill any running Python processes)

Delete the main Python folder under drive C.

Using CCleaner (or a similar application), use the "Tools → Delete" function to remove Python (if it still exists after deleting the folder)

Then go to the registry window in CCleaner and clean the registry. Now Python will completely disappear from your computer.
