Have you tried with a variety of unzippers? Maybe 7zip can do it if built in windows can't... – outsideblasts Oct 10 '09 at 7:08

WinRar repairs damaged archives.

WinRar is shareware, but available as an unlimited trial (if you don't register and pay, the program simply "nags", it doesn't stop working).

There's also DiskInternals ZIP Repair

DiskInternals ZIP Repair has built-in extraction features that allow it to extract partially damaged and restored files.

I have no idea if it is available on windows, but you did ask for an open source answer (that's probably available under cygwin though).

You might use the zip command itself (at least under linux):

If only some bits are missing (incomplete download):

zip -F your_corrupted_zip_file.zip

If the archive's data is damaged (wrong data) (this command is less reliable):

zip -FF your_corrupted_zip_file.zip

Info-Zip' zip command also has a Windows version, no need to use cygwin. They even have an Amiga binary... – sleske Jan 6 '10 at 11:41
