F5 WAF Tester tool

Given the "c" path and "python38-32" that implies you're running this script from Windows and using the 32 bit python executable. Windows isn't listed as a valid pre-requisite for the script on the main github page, https://github.com/f5devcentral/f5-waf-tester - ubuntu/kali/fedora only.

Prerequisites

Python 2.7+

Python package control (pip):

Ubuntu/Kali, 

sudo apt-get install -y python-pip

Fedora, 

sudo dnf install -y python-pip

It runs without issue for me on Windows 10 WSL-Ubuntu, python 2.7.17, 64 bit.
