Hang during startup

[dacendale]

GeometryPack is hanging during start up of ComfyUI protable. Tried removing the directory and reinstalling and same issue. Also tried running the pip install requirements from the directory and it completed without errors. Here is the log:

I'm reluctant to run this as admin to see if it resolves the error message. Can anyone provide insight into what the long path names are required for?

Tried running as admin and it still hung. After pressing ctrl-c the next message with simply that long path names are enabled.

[PozzettiAndrea]

@dacendale Hi! :) the long path names is because if you look at the bpy install it gets freakishly long names that make importing them impossible. Feel free to verify by looking at the bpy wheel. Regarding the problem itself, please show me your install logs!

[dacendale]

Certainly, thanks for the quick response on this. Here is the end of the log after using the install from the manager:

This is from the console output, I'm not familiar with any log file that is written by the node manager itself.

[PozzettiAndrea]

@dacendale Could you try installing the latest numbered version from the ComfyUI Manager (version = "0.2.16") and letting me know how it goes? :) Sorry it's been a while!
