This is way too vague. Please read the sidebar and provide a clear and complete list of exact steps to reproduce the situation, step by step, so that nobody needs to guess or interpret how you performed each step, what happens after performing these steps to reproduce, what you expected to happen instead, a full link to a web address where the issue can be seen, the exact full MediaWiki version, exact PHP version, exact database software name and version, etc., and what exactly makes you think that something "is not working".
The real issue is that I downloaded the latest version of MediaWiki in a .zip file, but upon extracting it, I discovered that the files were corrupted. I also tried an older version I had, thinking it might be an issue with the new version, but it turned out to be corrupted as well. At first, I thought it might be a problem with my system, so I ran some corruption detectors, only to find out that the files were indeed damaged, not my system.
If the local software on your machine corrupts zip files, then there is nothing that can be fixed in MediaWiki itself.
