The MEK(Mozz Editing Kit) is a collection of tools made for editing Halo. Originally created by MosesOfEgypt and now maintained by Sigmma.
Installation:
Install a Python version of 3.6 or higher. You can get it on Windows by opening the "get_python_3.8" shortcut in the install folder.
Run MEK_Installer.pyw
Choose whether or not to install the MEK's libraries in a portable fashion (to a local directory) or to the machine you are running. Make sure that "install up-to-date MEK" is checked so it will download the rest of the MEK to the current directory.
Click "Install/Update"
If the installer fails because it says pip is not installed, close it and run get-pip.py to install pip. When it finishes, go back to step 2.

Troubleshooting:
If you encounter an error while running the MEK installer, make sure to check the "show detailed information" box and run it again. Send me a message with the output and your system's information so I can fix it.
If programs wont run at all, Python might not have been added to your system's PATH environment variable. Google how to fix this, or run the python installer again to uninstall it and re-install it with at least the options specified above ticked.
If programs wont load or save tags then you have a permissions issue where python isn't being allowed to modify/make files in the directory you are in.
The way to fix this is to move your modding folder out of program files, or by updating the permissions for the folder to be editable by non-admin users. Window's User Account Control is very picky and mean about how things get edited in protected folders.
