Unable to launch jupyter notebook via CMD without Anaconda

Due to company policy, I can’t install anaconda in my pc and I know I could launch the notebook via Command as long as I have the notebook installed correctly.

I have installed the notebook with the command provided here.

However when I tried to launch the notebook via CMD, I got the below error message:

C:\Users"Username">jupyter notebook
Script file ‘C:\Users"Username"\AppData\Local\anaconda3\Scripts\jupyter-script.py’ is not present.

It seems like a file is missing but I have already reinstalled the notebook a few times.
