Q:

Cannot install Python 3.4.5 on Windows 10

I already have python 3.5 installed on my computer. But I need to install python 3.4.5 on my computer in order to use lxml. I tried to install by running setup.py file in the download folder as below:
C:\Users\Juan\Downloads\Python-3.4.5>setup.py

But got the error message:
Traceback (most recent call last):
  File "C:\Users\Juan\Downloads\Python-3.4.5\setup.py", line 26, in <module>
    sysconfig.get_config_vars()['CFLAGS'] = cflags + ' ' + py_cflags_nodist
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

I have no clue what is the issue. Do I need to uninstall py 3.5 first? Any help will be appreciated.

A:

Well First, You should uninstall python 3.5, and Im pretty sure there is an exe you have to use to install, if I am correct.
