Smart Factory Starter Pack

Hi Guys,

I've installed the latest IRIS 24 and trying to setup the Smart Factory Starter pack following the link below and would like to confirm a few things:

GitHub - intersystems/InterSystems-IRIS-Smart-Factory-Starter-Pack: ASP - OEE Dashboard
 

So I created a new OEESP with its database in IRIS, then the second step is to install PythonGatway but doesn't that come out of the box with IRIS latest versions? if not, it says I must install Python 3.6.7 which doesn't exist anymore

   and last step 3 with installing the classes, I went to link below and not sure how to install the classes, I got the below error when running it the iris export builder  ?

Thanks
