Wing IDE + Python 2.4: no module named functools

Question

I need to use Python 2.4 to be compatible with an old Python extension not easily replaced. So I installed Python 2.4 and wing IDE 101 v.6, and directed Wing to use that Python (it wasn't automatic). I have done this combination many times before on Windows 7 and Windows 8 machines, but this time I did it on Windows 10, and I'm seeing a brand-new error: the moment the shell starts it reports "No module named functools". Full stack dump below. Any suggestions on how to configure things to make this work?

Traceback (most recent call last):
  File "C:\Program Files (x86)\Wing IDE 101 6.0\bin\wingdb.py", line 875, in main
    winghome, user_settings = _GetWingDirs(orig_sys_argv)

Answer 1

Functools did not exist until version 2.5:

From the docs

New in version 2.5.

Answer 2

Wing 6 does not support Python 2.4. You'll need to use Wing 5 for that.
