[ClonkAndre]

This is the code i'm using How can i fix this issue?

using (ZipFile zip = ZipFile.Read(fileLoc)) {
zip.ExtractProgress += Zip_ExtractProgress;
                        
totalFiles = zip.Count;
progress = 0;

foreach (ZipEntry entry in zip) {
    progress++;
    zipEntry = entry;
    entry.ExtractExistingFile = ExtractExistingFileAction.OverwriteSilently;
    entry.ZipErrorAction = ZipErrorAction.Skip;
    entry.Extract(instance.s1_SelectIVExe.IVInstallDirectory, ExtractExistingFileAction.OverwriteSilently);
}
}
