procedure ZipInstall(const sourcezip, destdir: string; 
splashwindow:TSplashWindow);
   var unzipper:TUnZipper;
   begin
     unzipper:=TUnzipper.create;
     unzipper.FileName:=sourcezip;
     unzipper.OutputPath:=destdir;
     unzipper.examine;
     splashwindow.FileCount:=unzipper.Entries.Count;
     unzipper.OnStartFile:=@splashwindow.OnStartFile;
     unzipper.UnZipAllFiles;
     unzipper.free;
   end;


(TSplashWindow is a form where I show the progress)

I never tried but if you want to use a stream, instead of setting 
FileName you can assign OnOpenInputStream and create a stream there.
