A self-extracting zip file can be opened on a computer which doesn't have WinZip or a compatible extracting utility. However, at certain times, when you try and extract information from a self-extracting zip file, you may receive an error. An error signals a possible corruption in the zip file.

If nothing works, it would be required of you to look for appropriate zip repair solutions.
