Whenever I try to install a library using Processing 4.3, I get an error “Could not move contribution to backup folder”. This happens at the end of an install. It is happening with any library install. I have tried searching forums for ideas, but could not understand what they were talking about or the question did not get a response. Thank You in advance
Based on the error message “Could not move contribution to backup folder,” it does seem likely that this could be a permissions issue. A common solution for this kind of problem is running the application as an administrator which is what solved it for the poster on this topic. It looks like you’re on Windows, so you can right-click on the Processing executable and choose “Run as administrator” the try the install again to see if that resolves the issue.
