Try the ComfyUI directory listed there - if that doesn’t work, please let us know. A fix for this issue is coming in the next release. ---

Still working on the next release, but if you’d like to keep troubleshooting, there are some steps below. The next release should resolve this issue. Try removing both `extra_models_config.yaml` and `config.json` from `%APPDATA%\ComfyUI`. When you next start the app, it will be in installer mode. Select a new, completely different path to install to, and run through the install / download process again. If you run into issues and are migrating custom nodes/extensions, try without. ---

Yep, you can just open file explorer in Windows, and type `%APPDATA%` into the address bar.
