can't uninstall Python 3.6 on windows 10

I installed python 3.6.2 recently on my windows 10 machine, but I cannot seem to uninstall it at all

The error I get is:

No python 3.6 installation was detected

then

0x800070643 Fatal error during installation

Things I tried

• c:\Users\USERNAME\AppData\Local\Programs\Python > delete folder, app still shows up
• Revo uninstaller > uninstall python 3.6
• Uninstall app normally through "add or remove" programs
• Delete Python36 environmental path
• Some combinastion of repair+modify and then uninstall... no go

How do I fix this?

I haven't tried doing any registry edits or using restore points yet though

It's also possible to execute the python3 installer again, you get option to repair or uninstall. Just choose uninstall, it will be done properly.

I uninstalled first which removed it from the list but none of the files. Go to the folder and delete and then delete from the start menu - seems to work.

If you got here because of this annoying message when trying to install a Python package because Python was installed by Windows (likely by Visual Studio), then you might want to keep reading...

WARNING: The script virtualenv.exe is installed in 'C:\Users{user}\AppData...\Python...\Scripts' which is not on PATH

Before you uninstall using the steps below, please read the beginning of my answer here first!!!!!!!! know the consequences! If your other Python environments rely on this, you might have to fix a few other things, so run a few commands and get the current details. You will only be able to install packages if you have the required set up, without having a site or global Python install.

pip config -v list
pip show virtualenv

Read this before the uninstall and know what you're getting into.

After you study a bit, you can uninstall from here. Merry Christmas!

Control Panel > Settings > Apps > Apps & features > use the Filter by menu, and select the drive containing the "WindowsApps" folder > Select the app and click the Uninstall button > Click the Uninstall button again
