In the _SaveSfxStub method (used to build a self‑extracting ZIP), the code attempts to read an embedded ZIP resource named Ionic.Zip.Resources.ZippedResources.zip. However, that resource is not actually included in the DotNetZip assembly, so GetManifestResourceStream returns null and ZipFile.Read(null) throws an exception. Users cannot generate any SFX stubs as a result.
`
// This line always fails because the resource does not exist:
using (ZipFile zip = ZipFile.Read(executingAssembly.GetManifestResourceStream("Ionic.Zip.Resources.ZippedResources.zip")))
{
// …
}
