Found this at the http://www.7-zip.org/faq.html#user_faq

--------------- start ----------------------------

Why can't 7-Zip open some ZIP archives?

In 99% of these cases it means that the archive contains incorrect 
headers. ZIP archives contain two copies of headers. 7-Zip reads both 
copies and won't open archives with incorrect data in the headers. Other 
ZIP programs can open some archives with incorrect headers, since these 
programs usually read only one copy of the headers, or they just ignore 
errors.

-------------- end ----------------------------

I hope this helps.
