How to Fix Native Error 00008 “invalid size or checksum”

Native error 00008 when working with a compressed archive means that either the archive is corrupted, or it’s using a format that your computer doesn’t understand. This error appears with a dialog box that gives you options to Abort, Retry or Ignore, but neither of them will let you work with the archive.
