Can't uninstall Python on Windows (3.4.2)

Question

I accidentally downloaded Python 3.4.2 a while back but I actually needed Python 2.7, so I deleted the 3.4.2 files and downloaded 2.7 instead. Now I need Python 3, so I tried to download it but I noticed that in the control panel in the Uninstall Programs section it tells me that the 3.4.2 from back then is still on my PC.

Every time I try to uninstall/change/repair/download a newer version I can't and it tells me

A program required to complete the installation can not be found...

I can not find any remaining files connected to any sort of Python in my PC. My operating system is Windows 10. Does someone know how to solve this?

Did you try downloading a .msi and just installing with that? python.org/downloads/windows — Padraic Cunningham

Did you try to reinstall the version you want to delete and then uninstall it afterwards ?

When you do this, always be aware that you re-created the uninstall information using a fresh install, in particular this may not contain all the necessary info to delete all the files of the previous installation. You can either check the files manually afterwards and/or try to recreate the installation and reinstall absolutely everything you installed before to uninstall. This is most likely to miss less things during uninstall.

Try to use the same .msi file (same version) for uninstalling as was used for installing.
