ZipArchive Corrupts Signed OOXML Files

Hi,

If i pass a path to a signed ooxml (office 2007 and up) file, after running the code below - office shows that the file is corrupt.

using (FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read))
{
using (ZipArchive zip = new ZipArchive(stream, ZipArchiveMode.Update))
{
}
}

Looking at the file, i have found that it changes the 'Version Made By' in the Central Directory File Header.

Is there any way to control it?
