You could also delete them. No need to keep anything. It's not broken the archive is packed using WinRAR5. This has something to do with the Sony Software. Don't install the latest version. It has nothing to do in which order you install the drivers. All drivers linked here are working fine. The problem is the software which comes from Sony and you really should use the latest versions mentioned in this thread. Why not? Every Sony specific driver mentioned here is for every Sony model out there.
