Decision Optimization

Hi, I am new Cplex started college student. I followed the steps from https://community.ibm.com/community/user/blogs/xavier-nodet1/2020/07/09/cplex-free-for-students and installed the ILOG Cplex Optimizer. Also I create a python 3.10 virtual env but when I run the command python -m docplex.mp.check_list I get the message : 

• system is: Windows 64bit
• * Python version 3.10.0, located at: C:\Users\User\Desktop\Projeler\ILP_çalışmaları\cplex_env\Scripts\python.exe
• * docplex is present, version is 2.30.251

How can I use un-limited version as a College student ?
