LoadLibrary error with Python

[Guilherme Tavares]

Hi,

I have been tinkering my orthanc windows server for a while, and was trying to set up a few Python scripts.

I downloaded the OrthancPython-Win64-Python3.8-1.0.dll and the correct (I guess) Python version (3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 23:11:46) [MSC v.1916 64 bit (AMD64)]).

I have put the dll on the plugin folder, but I'm getting this error message while I try to load the server (in red):

This error probably reflects the fact that the DLL of the Python 3.8 interpreter is not present in your PATH. Make sure that the Python installer has updated the environment variables for your user.

You can use tools such as "Dependency Walker" to debug such issues:

HTH,

Hi Sebastien,

Thanks for the response. 

The problem was with my PATH, somehow when I installed Python on my windows it only set on my user and then deleted it, once I put it on the "System Variables" it started working again.

Regards!
