ExtractExistingFileAction.OverwriteSilently is not overwriting the files in a given folder

I have an update solution for an application that uses the DotNetZip API ( link ) for handling ZIP files. One of the methods used is to overwrite files in certain folders as follows.

 ZipFile zipFile = ZipFile.Read(file);
        {
            foreach (ZipEntry zipEntry in zipFile)
            {
                zipEntry.Extract(@"C:\IASD\CantinaEscolar", ExtractExistingFileAction.OverwriteSilently);
            }
        }

Where: @"c:\IASD\CantinaEscolar" is the location where the files that are inside the zip (file) will be unzipped.

If the directory already has a file with the same name as it will be unzipped, the application is returning an error for the file already in the directory.

System.IO.IOException: The file 'c:\IASD\CantinaEscola\nomedoarquivo.exe' already exists .

Should this OverwriteSilently method not overwrite the unzipped files silently (without user confirm request)?

Or, is there any way to force this override into the directory (of the -f type or something like that)?

If you have any other tips on how to do this, I'll be grateful.
