We have seen a few PCs that have an issue with unzipping downloaded data and have created a file that adjusts the unzip process. EZ Update Error: Install error: ICSharpCode.SharpZipLib.Zip.ZipException: Length not available for the current entry at ICSharpCode.SharpZipLib.Zip.ZipInputStream.get_Length() at ATP.Navigator.Installer.Utilities.UnzipZip.extract() at ATP.Navigator.Installer.Utilities.UnzipZip.Execute(Boolean execute) at ATP.Navigator.Installer.Utilities.InstallStep.Execute() at ATP.EZUpdate.Installers.ContentProcessor.InstallGroup(ArrayList installSteps) Fix: Download the attached file and run once. It will replace the file ICSharpCode.SharpZipLib.dll. The one that already exists will be backed up to ICSharpCode.SharpZipLib.dll.bak.
