  In Version 3.2.0.0 the Workbook Open method fails to open a document from a memory stream stating that the ‘File contains corrupted data.’. In Version 3.0.4.0 the Workbook Open method opens from a memory stream without issue.

  Is opening from a memory stream in 3.2.0.0 no longer supported or might this be an issue from an underlying component?

  Here is the stack trace from the issue:
  
  at MS.Internal.IO.Zip.ZipIOEndOfCentralDirectoryBlock.FindPosition(Stream archiveStream)
  
  at MS.Internal.IO.Zip.ZipIOEndOfCentralDirectoryBlock.SeekableLoad(ZipIOBlockManager blockManager)
  
  at MS.Internal.IO.Zip.ZipArchive…ctor(Stream archiveStream, FileMode mode, FileAccess access, Boolean streaming, Boolean ownStream)
  
  at MS.Internal.IO.Zip.ZipArchive.OpenOnStream(Stream stream, FileMode mode, FileAccess access, Boolean streaming)
  
  at System.IO.Packaging.ZipPackage…ctor(Stream s, FileMode mode, FileAccess access, Boolean streaming)

  Thank you for any help you can provide.
