    } else {
        var chilkat = require('@chilkat/ck-node21-win64'); 
    }

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var zip = new chilkat.Zip();

    var success = zip.OpenZip("test.zip");
    if (success !== true) {
        console.log(zip.LastErrorText);
        return;

    // entry: ZipEntry
    var entry = zip.GetEntryByName("hamlet.xml");
    // Assume entry is non-null.  If GetEntryByName failed
    // to find the entry, it returns a null reference.
    entry.FileName = "hamlet2.xml";

    entry = zip.GetEntryByName("helloWorld.pl");
    entry.FileName = "hw.pl";

    // Now unzip to the "test" subdirectory, under our current
    // working directory:
    var numFilesUnzipped = zip.Unzip("test");
    if (numFilesUnzipped < 0) {
        console.log(zip.LastErrorText);
        return;
    }

    // The filenames within the .zip are unchanged, but it unzipped
    // test/hw.pl and test/hamlet2.xm
