I just noticed the edited version of your comment. I'm glad you got it extracted. I hope you don't have any other issues. Cheers!
I'll keep checking a few things but I can't change the path of certain things. Some libraries in the app are hard coded with those paths and I can't change them without breaking stuff. Hopefully it's just an edge case on your PC. The strange thing is that the file in the error is a file that was already there in the old version too. Nothing changed with that part of the app in the experimental update. So I don't know why it would extract in one version but not another. Thanks for the heads up though, it's appreciated.
