   Routine Description:
      The file name is generated based on the calling machine's name
      and the build number being installed. In the "before" case, the generated
      name is saved to c:\setuplog.ini, and this name is in turn read in
      "after" case.

   Arguments:
      Where to write the file.
      The build.
