Then almost certainly the file is corrupted or incomplete, just as it 
says.

If you downloaded it via FTP, did you remember to use binary mode? If 
you downloaded it via HTTP, did you right-click to save to a file?

To be sure, get a cryptographic hash (e.g. sha1 or md5) from the file on 
this machine, and compare it to the hash of the file on the other 
machine. If the hashes are different, the two files are definitely 
different. Also, many download sites publish the sha1 or md5 of the file 
you're downloading, so you can compare to that too.

I don't use Windows so I don't know what utility you'd need to install 
to get an sha1 or md5, but I'm sure there must be plenty around.
