In package contents i shows in contents "Info", "MacOS", "PkgInfo", "Resources" and "Versions", am i missing something?
No, you can try redownloading it, but I doubt it'll solve anything. Your best bet is to google the error and look up a solution. I have no idea about macs so I can't help you.
Will try redownloading it then
Or i will try downloading the windows version
Nah doesn't work, guess i can't download
