Hey friends, This is my first time to install ComfyUI. After finishing the installation, I try to ‘Batch Model & Extension Downloader’, then I get this: Unable to start ComfyUI Desktop v0.4.16, any suggestion what to do?

[Schermafbeelding 2025-02-03 165142] Hi, TNX for your reply. Please see attached. Hope to find a solution :wink:

This seems a generic error page from ComfyUI. can you also send the screenshot of what you have seen when you clicked on Open Logs : )

Hi, Tnx again for your reply. Please find attached: screenshot of what I see when I click on (Open Logs). [Schermafbeelding 2025-02-05 202136]

Hi Again, I have just saved some log files as seen above, but I am unable to upload an attachment as I am a new user ;-(

I will try to do it in this way: [Schermafbeelding 2025-02-05 203737]

@Badia Hey can you screenshot the part of the logs at the bottom of the file? Or email them to support@comfy.org
