pip install giraffez not working on Windows -> errors + warnings

[intrapreneur-dimy]

Dear professionals,

I am trying to install giraffez on Windows since one week now.
No chance on Win10 nor on Win2012R2 -> same errors! -> both x64 OS.
Python 3.9 x64

Errors + warnings:

Do you have an idea why it does not work?

Which MS Visual Studio Build Tools are required?
Which Teradata TPT and CLI (or TTU) versions are required?
Which Python versions are working well with giraffez? Are there maybe new limitations somehow?

Thanks in advance.

Best regards,
