    //  This example creates a .exe that downloads the .zip from
    //  http://www.chilkatsoft.com/testData/testWithSetup.zip,
    //  unzips it, and runs the setup.exe contained within.
    //  This is an actual URL that can be tested. The setup.exe
    //  is a do-nothing program that simply displays a dialog box
    //  with an "OK" button.

    //  Set the AutoTemp property to create an EXE that

    //  extraction:
    //  Note: You may download the .zip at http://www.chilkatsoft.com/testData/testWithSetup.zip
    //  and examine it. You'll see that the "setup.exe" has a path
    //  within the .zip, therefore you must specify the path as it
    //  exists within the .zip:
    zip.put_AutoRun("bin/setup.exe");

    //  a progress dialog.
