Almost universally, this means that either MojoSetup couldn't read 
itself to self-extract files (check file permissions), or the file 
appended to the binary got corrupted (if it's a .zip file, the last few 
bytes of the file tell us where the PkZIP data structures can be found. 
An incomplete download will cause this for certain).
