What's problem in it?

When I have loaded lunchbox , This massage pop up. and It always pop up when I would open grasshopper. +lunchbox is normally functioned.
Please tell me what is problem in there?

You may have two locations where lunchbox is installed, and grasshopper is loading both giving this error. Try to find both locations and delete one of them.

Thank you…! But I can find another file, ㅠㅠ

I’m sorry, I don’t understand your latest comment.
You can inspect folders where grasshopper loads its plug-ins from using the GrasshopperDeveloperSettings command in Rhino. This gives the following dialog, where you should click “Valid Folders” (with the :eye: )

These folder(s) contain the locations where grasshopper may find its plug-ins. Only one of these folders should contain the lunchbox plug-in.
