I copy the two sample codes and run at office server, they work with a small size zip file.
then I sent to two client server , run the same code with same the zip file

one client server work well, the zip file upload successfully and can unzipped successfully
one client server work fail, the zip file but it is corrupted.

I found some sites about possible problems cause the processing fail:

Site 2
NOTE - YOU MUST HAVE VBSCRIPT v5.0 INSTALLED ON YOUR WEB SERVER FOR THIS LIBRARY TO FUNCTION CORRECTLY. YOU CAN OBTAIN IT FREE FROM MICROSOFT WHEN YOU INSTALL INTERNET EXPLORER 5.0 OR LATER.

WARNING : THIS SCRIPT WILL NOT WORK IF YOUR SERVER HAS SCRIPT VIRUS CHECKING ON!!!!
TURN THE SCRIPT BLOCKING OFF WHILE THIS RUNS.
ALTERNATIVLY USE A DIFFERENT SERVER FOR MAIL!
