problem installing numpy (Windows XP, Python 3.4)

[abubelinha]

I use Python 3.4 in Windows XP 32bits and I have successfully installed many Python packages using binaries provided by @cgohlke .

But for some reason I am not being able to install the basic package Numpy+MKL which is required by many other packages.
I have the feeling that my problem is related to the fact of having a "+" symbol inside the package name:

C:\python34\scripts\>pip install numpy-1.16.6+mkl-cp34-cp34m-win32.whl
DEPRECATION: Python 3.4 support has been deprecated. (...).
WARNING: Requirement 'numpy\u20111.16.6+mkl\u2011cp34\u2011cp34m\u2011win32.whl' looks like a filename, but the file does not exist
ERROR: numpy\u20111.16.6+mkl\u2011cp34\u2011cp34m\u2011win32.whl is not a valid wheel filename.

Actually, if I change the file name, then installation begins but I suspect the file name has importance here because not all names work (the one I tried I removed the mkl part, of the name, but then mkl package was missing).
I would be grateful if someone could help me this problem.

In the mean time, I also tried to install pipwin (as it is supposed to facilitate installation of these packages). But a different error raised here, which I suspect has nothing to do with numpy package:

c:\python34\scripts\pipwin install numpy

Any hints on how to solve this?
Thanks a lot
