Error message when first running start.bat file

[FATCullen]

Upon running the start.bat file, after installing several other files, it gives the following error message and ends the process

Any following attempts at running the file results in a string of "requirement already filled" message, and attempting to run the main.py file directly just results in multiple error message
Any help would be much appreciated, thanks.

try opening cmd in that folder then type "python main.py"

I have, but it just comes up with Traceback (most recent call) and list where things went wrong

Are you able to copy-paste the entire output into a reply to this issue? That way we will be able to see the entire error....

Looks like an issue with it trying to install necessary python packages on first glance.

Actually I can see it. Open PowerShell as an admin, and in it, run pip install pip --upgrade, then pip install billiard --upgrade, then retry running start.bat.
