Hi, I am getting the following error after installing the v2 client [ python version is 3.6.9 and pip3 version is # python3 -m pip --version
pip 20.0.2 from /usr/local/lib/python3.6/dist-packages/pip (python 3.6)] [ I am using the Ubuntu on Windows subsystem for Linux for python 3.6 and Kali for WSL for python 2.7 ] :

:~# arcsight-taxii-client -v

I tried installing on a separate system with python 2.7 and am getting another error while installation itself :

Running setup.py install for subprocess32 ... error

@Bart  

Has the requirements file been updated ? I get the following error when trying to install.

I have a standard OS install of python 3.6 and pip3,setuptools and wheel 

When I try to install arcsight_stix_taxii.zip with pip3 I am getting the following error :

is this module actually missing? I removed it from client2.py and the client started successfully however it hangs on Discovery and there is no network traffic

Is there any changes to the STIX/TAXII integration for ArcSight?
The client is no longer available in the Fos Wiki and the Marketplace L1 Threat Intelligence documentation page stop at Step 1
