Create a directoy on your hard drive. 
Name the directory Fooocus
If you do not have an Install directory, create a directory named Install.
Inside the Install directory, create a directory named Ai.
Download the contents of the Ai directory into the Install\Ai directory.

Open the install\ai\Winrar directory on your machine.
Install winrar-x64-624.exe
During the install you will be asked which files to associate with winrar.
Make sure that .7z is selected. 

Open the install\ai\Python directory
Install python-3.12.1-amd64.exe
*** Importaint. During the install you will be shown a dialog box with a checkbox to add path to environment. Maje sure that the checkbox is selected. We want the path to be modified.
Open the install\ai\LM Studio directory
Install LM+Studio-0.2.9+Setup.exe
Open the install\ai\Fooocus directory

Open winrar.
In winrar, open the Fooocus_win64_2-1-791.7z file.
Select extract, then select the Fooocus directory on your hard drive as the location to extract the files.
After the files are extracted, using windows file manager, open the Fooocus directoy.
Click on run_realistic.bat or run_anime.bat or un.bat.
If the bat does not run, then most likely the path to Python is not set in your environment variable.
After the instial setup of downloading Stable Diffusion XL databases, a web ui will open.
I use the advanced options.

You now have a robust Ai system. 
LM Studio for text generation and Fooocus for text to image generation.
