The winzip version that I downloaded to unzip/untar the Openmash source code is 7.0 SR-1 which is a shareware. You can download it from the following link: http://download.cnet.com/downloads/0-10097-100-896913.html?tag=st.dl.10001.pop .10097-100-896913 Note: Winzip did NOT unzip/untar our file. Error message: 0 files unzipped Regards, Wilson Cheng
