Hmm, it seems to work fine on my little Macbook Air. Did you get any kind of error message, and did you give the app permission to access the other files in the zip?
So that problem was caused by the macos archive utility messing up the unzip. But now the main .app can't find the app bundle.
Do you have the error message?
