With great enthusiasm, I present to you the easiest Flux install you could possibly find.
With your already installed SDForge software found here:
https://github.com/lllyasviel/stable-diffusion-webui-forge/releases/download/latest/webui_forge_cu121_torch231.7z
Simply download the file below ( dl-flux-models.bat ) to the same folder as update.bat and double click it. You can then choose to download / remove the models at will.
When it is done, click run.bat and follow the directions in the video tutorial.
SO EASY!
