Self-extracting ZIP (and other archive format) files from DOS, Windows, OS/2, etc are usually an executable program with ZIP file appended. The stub program knows to seek to the end of its executable data to look for the archive it is to extract and unzip (etc) are able to detect this stub and bypass it. I googled the file wg511v2_3_2.exe and downloaded it. It is a InstallShield program, containing an MSI containing a CAB. AFAIK there are no Linux programs that are able to unpack -current- versions of InstallShield. I am on Windows XP right now (at work), I have unpacked the contents and can email them to the OP or upload somewhere if you'd like. Let me know.
