I am unable to install Python 3.4.2 amd64 on Windows as the installer exits with an error stating that it cannot run a required program.

Can you copy the exact error that you got?
Have you tried redownloading it, and/or checking with a different version (x86 or Python 3.3)?
Do you have admin privileges on your account?

It turns out that Windows Installer failed to remove the Python 3.4.1 installer entry from the registry when I uninstalled that version previously. Deleting the entry fixed the install.

Basically, Windows borked it.

I've just come across the same problem.

I uninstalled Python 3.4.1 amd64. There were other things installed in that version, so some stuff remained.

I then tried to install Python 3.4.2 amd64, but it failed (same problem as Zac).

I ran the Python 3.4.1 amd64 installer to repair it and then the Python 3.4.2 amd64 installer again. It worked.

This is on Windows 8.1 Update 1, 64-bit.

I had no trouble ungrading 3.4.1 to 3.4.2 with win7 up to date with 'required' updates and most recommendedupdates.

@Terry: Just to clarify, I didn't have a problem installing over Python 3.4.1, only with uninstalling Python 3.4.1 (with other stuff installed there) and then installing Python 3.4.2.

This was marked as 'fixed' almost two years ago. I tried to install 3.4.3, uninstall 3.4.3 and install 3.4.4 again in Win 10 and it worked fine for me. I guess this was left open accidentally.
