Which installer did you download?

I've installed both the 32-bit and 64-bit versions of Python 3.6.0 
(using python-3.6.0.exe and python-3.6.0-amd64.exe respectively) and 
they're both working perfectly.

In <python_folder>\Lib there's a folder called "encodings". If I rename 
it, Python fails. Does that folder exist? Does it contain a load of .py 
files? If not, there's something wrong...

Maybe your installer got corrupted somehow.

Uninstall it, check that all traces of that installation have gone, 
download the installer again, and try installing it again.
