Hey Stefan,

From what I can tell, this path variable issue is a common issue that MANY users are experiencing.  Would it be possible to provide more specific instruction? Perhaps more detailed documentation? Or a video post to Youtube?

I've read through all the docs on the python binding & I followed the instructions:

---I've downloaded Cache (C:\InterSystems\TryCache\bin)

---My system meets the client requirements for the python binding (https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY...)

---My 64-bit windows environment & paths are setup to run Microsoft C/C++ with Visual Studio 2017. In addition my vcvars64.bat path is set to C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\VC\Auxiliary\Build

---I execute the setup3.py file in my C:\InterSystems\TryCache\dev\python directory. It runs and prompts me for the cache installation directory, in which I paste in C:/InterSystems/TryCache/bin. 

--I then run test.py and this is what I see in powershell. A message that seems to say python doesnt know anything about the intersys module.
