Upgrading Comfy Labs

If you are needing to update Comfy-Labs, follow these steps. Nothing in your install dir, models, or settings will be touched – you are only swapping the small app shell.

Steps

Quit Comfy Labs. Close the app window. If you want to be extra safe, open Task Manager and confirm no Comfy Labs.exe or python.exe processes are still running.
Download ComfyLabs-vX.X.XX.zip from the same place you got the previous build (the Download button on the in-app update banner, or whichever distribution page your beta access points at).
Unzip to a new folder next to your current one. For example, if you have:
```
W:\ComfyLabs-vX.X.XX-OLD\Comfy Labs.exe
```
unzip the new one to:
```
W:\ComfyLabs-vX.X.XX\
```
Do not overwrite the old folder. Putting them side-by-side gives you an instant rollback if anything goes wrong.
Launch W:\ComfyLabs-vX.X.XX\Comfy Labs.exe.
The app should:
- Skip the wizard (Config found; skipping wizard will appear in the log)
- Open straight to the welcome screen with Open Workflows enabled within a few seconds
- List all your installed workflows as Ready in Settings
- Show Start ComfyUI in the toolbar (the backend is lazy-spawned on first request; cold start is 60–120s)
Once you have confirmed ComfyLabs-vX.X.XX works, you can delete the old W:\ComfyLabs-vX.X.XX-OLD\ folder. It is about 200 MB of dead app shell. Optional – it does no harm sitting there.

What stays untouched

Everything outside the app folder you replaced:

What	Where
Python venv (PyTorch + CUDA wheels, ~5 GB)	`<install_dir>\runtime\`
Bundled Python 3.12 base	`<install_dir>\python-runtime\`
Bundled MinGit	`<install_dir>\git-runtime\`
ComfyUI clone with custom nodes	`<install_dir>\comfyui\`
All downloaded AI models	`<install_dir>\models\`
Your generated outputs	`<install_dir>\outputs\`
Pip wheel cache	`%LOCALAPPDATA%\Comfy Labs\pip-cache\`
App config + “wizard done” marker	`%APPDATA%\Comfy Labs\config.json`
HuggingFace model cache	`%USERPROFILE%\.cache\huggingface\`

You will not re-run the wizard, re-download models, re-install PyTorch, or rebuild custom nodes. Total upgrade time should be under a minute.

Do NOT use the uninstaller

Uninstall-Comfy-Labs.bat is for complete removal – it deletes your venv, ComfyUI clone, all models, and the config. For a version upgrade you do not want any of that. Just unzip and launch.

If something goes wrong

Roll back by relaunching the old W:\ComfyLabs-vX.X.XX-OLD\Comfy Labs.exe. Both versions read the same config and install dir, so switching back is instant.

Then click Support Log in the toolbar to export a fresh report ZIP and send it over.
