Removing an addon (C3)

Hi,

I'm trying to remove an addon in C3 from someone else's project but the project still complains that it is required (when I close it and try to reopen the project it throws an error that the addon is missing). I think the behavior was used on only one object and I removed it. Is there a way to find out where an addon is used? Or any other suggestions how to convince the project not to use the addon?

Thanks,

Zsolt

Found the answer. I downloaded the project, renamed as .zip, unzipped it and ran a search on the files for containing the name of the addon. I found it in a json. I missed one of the text objects that still had this behavior on. So, it's user error :)
