Problem? Issue? Go to StackOverflow

This location (CodePlex) for the code-base has been long-abandoned by the original developer. The continued "sponsorship" by Xceed, despite their own competing commercial project, makes me think something is up here. Since 2011 the only active development has been happening on an unsigned fork hosted on GitHub.

But that's beside the point. You came here because you have an issue with DotNetZip. But this is not the place. You should go to StackOverflow.
