Hi guys. I am trying to use this python example project to understand the API's usage. After putting in the key and the license, when I run the Python_Demo_MulitThreaded.py file, It gives me this error.

Could someone please help me resolve this error?

From googling, I found out that it may be a 32 - 64 bits mismatch. And honestly, I don't understand how to solve it
