IRISPIP Cryptodome C++ Error

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

E:\HealthConnect\20201\bin>irispip install E:\HealthConnect\20201\Mgr\python\pycryptodome-3.18.0.tar.gz --target E:\HealthConnect\20201\Mgr\python pycryptodomex --no-binary :all

However, the required C++ version is installed on this system: See screenshot

Can someone explain what I am doing wrong? Or is it the offline install? Is it also possible that the Python version in IRIS is out of date?

Kind regards
