If it's WinZip, it costs money to use and I'm out of days for the free trial. I'm also trying to open it as an archive, but a pop-up says it's unreadable.
I'm not sure whats happening sorry, there does not seem to be any issues on my end and other people have been fine with it! I use win rar myself which works and if I right click on the file and go "Open With > Windows Explorer" that works too!
