The following file is generating an error (0xc0e90002) since i updated ComfyUI using "update_comfyui_stable.bat" :
...\ComfyUI_windows_portable\python_embeded\Lib\site-packages\llvmlite\binding\llvmlite.dll

Version :
ComfyUI: v0.34.0
(2026-08-25)
Manager: V3.41

Hi @Christophe-Pacaud, thanks for the report. 0xC0E90002 is a Windows "Bad Image" error, which means Windows refused to load llvmlite.dll because the file is corrupted, incomplete, or blocked by security settings.

A couple of things that will help narrow it down:

1. When does the error appear? Right at ComfyUI startup, or only when you run a specific workflow/nodes? A screenshot of the full error dialog would help.
2. This DLL is not part of core ComfyUI. numba (and its dependency llvmlite) is pulled in by custom nodes — WAS Node Suite and Jovimetrix are two popular examples. The portable updater runs git pull + pip install -r requirements.txt, and if a custom-node dependency got upgraded to an incompatible version (e.g., a newer llvmlite that needs a matching numba, or a numba that requires an older NumPy), the DLL can end up broken.

Suggested fixes (run from your ComfyUI_windows_portable folder):

• Reinstall a matching numba + llvmlite pair:
  .\python_embeded\python.exe -m pip install --force-reinstall numba llvmlite
  (numba pins a specific llvmlite version, so installing them together avoids mismatches.)
• If the "Bad Image" dialog still appears, it may be Windows security blocking the freshly-updated DLL:
  • Right-click llvmlite.dll → Properties → Unblock
  • Check Windows Security → App & browser control → Smart App Control (Windows 11 can block unsigned DLLs written by updaters)
  • Install/repair the latest Microsoft Visual C++ Redistributable: https://aka.ms/vs/17/release/vc_redist.x64.exe
• If the error only happens with certain nodes, find which custom node depends on numba (check your custom_nodes folder or ComfyUI-Manager) and update or disable that node. General troubleshooting guide: https://docs.comfy.org/troubleshooting/overview

Let us know what you find — happy to dig further.

Hi, I have a question and haven't been able to receive a direct answer. Maybe this will work. I'm in the US and I currently have a Higgsfield subscription. MiniMax H3 is one of the video models available. According to Higgsfield, I own the videos generated and am free to utilize them commercially, although I've come across information online that refutes this claim. Before putting myself in any legal issues, I'd like a direct answer to whether or not I'm able to use the videos on my monetized YouTube channel? Thank you

Hi @ben-2364, and sorry for the slow answer on this one. I work on the ComfyUI team at Comfy. We run this docs site, so I can speak to the model and licensing side, but I'm not your lawyer and I can't speak for Higgsfield.

There are two separate licenses in play, and I think that's where the conflicting information you've read comes from.

1. Your Higgsfield subscription. Higgsfield's Terms of Use (Section 4.4) state that they do not claim ownership of your inputs or outputs and do not restrict commercial use of outputs, and their help center says that applies to all plans and explicitly includes YouTube monetization. That is the grant you'd be relying on. Two things worth doing: save a dated copy of those pages, and ask support@higgsfield.ai to confirm it in writing for your specific case, something like "outputs generated on my current plan may be used on a monetized YouTube channel, including in client work". Their written answer is what you'd point to if a claim ever came up.

2. The MiniMax model license. How H3 is served changes which terms apply underneath the platform.

• If a platform calls MiniMax's hosted API, your outputs sit under that platform's subscription terms; the open-weights model license is not the relevant document.
• If a platform downloads the open weights and hosts them itself, the MiniMax H3 Community License applies. That license does not grant rights in the US: commercial use of locally generated outputs requires a MiniMax commercial license, and Comfy is the only official reseller for it (https://comfy.org/minimax/license). This open-weights route is the usual source of the "you may still need a license" claims you've seen online.

I can't tell you which route Higgsfield uses, and they're the ones who can. So the questions worth putting to their support are: is H3 on your plan served through MiniMax's hosted API or from self-hosted weights, and do outputs from my plan carry full commercial rights for monetized channels and client work? Get both in writing, and use watermark-free downloads where your plan offers them, since watermark terms often differ from usage rights.

If you ever move to running H3 locally in ComfyUI instead, the commercial license above is exactly the thing you'd need for commercial work.
