[Zope] WIN32 Z ODBC unpacking Question:

Another Newbie Question: How does one uppack the (ZODBCDA-3.0.3-win32-x86-python-1.5.1.tgz) file in Windows NT Workstation? I usually use a tar command in RedHat Linux? The instructions tell me to "Extract" in a top-level directory. I assumed that refered to dropping the file into c:\program files\Zope\ZODBCDA-3.0.3-win32-x86-python-1.5.1.tgz. I tells me this is a BINARY release (TO ME THIS MEANS AN EXTENSION OF .COM OR EXE? It then tells me to restart Zope. As a service i STOP and then START. What am I missing?
