Unable to unistall python 3.5 on windows

0

I am trying to uninstall windows 64 bit python version on my Win7 laptop but unable to do so.

It detects an installed version so it provides the option to modify, repair or uninstall. But on initializing uninstall it says "No Python 3.5 installation was detected".

I have tried doing a repair and then uninstall but to no avail. I have also tried several solutions mentioned online but nothing works.

Following is the log:

The solution that worked was clicking repair from the installer and let it fail. After it failed, I uninstalled it and re-installed it and it worked fine.

All steps done through the standard installer.
