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

Have you tried install and then uninstall? – Stephen Rauch – 2017-08-07T15:20:56.640

ya I can't install either now since it can't find my installation, and I can't uninstall since it can't find my installation – Vincent Tang – 2017-08-07T15:23:18.940

I ended up just using a restore point so problem solved i guess? – Vincent Tang – 2017-08-07T15:23:34.797

Solution:

UNHIDE ALL FOLDERS BEFORE FOLLOWING DOWN...

Go to C:\Users\ (Current User Name)\AppData\Local\Programs
Delete Python Folder
Go to Control Panel >> Uninstall a Program
Right Click on Python and then Change/Modify
Click on Repair Python. Note: This will Fail but be Patient
Now Again go to step 3
Now, after step 3, uninstall Python

Congratulations!! Uninstalled!!

Now Install a new fresh version

Happy Coding! Happy Programming!!

3I tried these steps, and it broke my install/uninstall. Luckily I had saved a zip archive of the folder before deleting it. A normal uninstall worked for me without issue. First try a normal uninstall, before trying these steps. – Felipe Alvarez – 2019-05-20T22:14:43.673

2@FelipeAlvarez I find it fun that you searched and applied a solution for a problem you didn't have. – Machado – 2020-01-29T19:42:51.803

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.

5That's a terrible solution, (I'm not blaming you but windows) – user1767754 – 2018-01-24T06:18:03.470

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.
