U4pak.py error

[Venusasaboi]

I am using the pack_tool to try to create a .pak file for models (so that I can play as a different character in Little Nightmares) however I keep getting an error whenever I click START_pack.bat
I have python 2.7 downloaded (as that's what I was told to use as pack_tool wouldn't work without it, yet it's not working? Any help would be greatly appreciated!!
Error:

C:\Users\User\Downloads>u4pak.py` pack Helios-WindowsNoEditor_MyMod.pak Helios
'u4pak.py' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\User\Downloads>pause

(I don't know what pack_tool is.)
This looks like you're calling u4pak.py as if it where an executable installed in %PATH%, but it is a Python script and probably not installed in %PATH%. You need to call C:\path\to\your\python.exe C:\path\to\u4pak.py pack Helios-WindowsNoEditor_MyMod.pak Helios (assuming you call this from the directory where Helios is in and where Helios-WindowsNoEditor_MyMod.pak shall be created).

Thank you I think I'm getting somewhere with this, however I got an new error :/

That is odd. Again, what is this pack_tool? Someone's fork of my code? If they've changed something nothing I say here might apply to what you're using. I can only help you with what I've wrote, so you could try u4pak.py from this repo. Download newest version: https://raw.githubusercontent.com/panzi/u4pak/master/u4pak.py

Or otherwise you need to ask that pack_tool for help. :D

I've written a new tool that doesn't require Python, but instead I provide a compiled Windows binary. It is faster, but has slightly different command line arguments and a feature for Windows users that don't want to use a terminal. Does that work for you?
