Error opening XLS from Stream

I can''t seem to open the attached file from a stream I get an error "Can''t open storage on LockBytes."; The code I''m using looks like: Stream fileStream = File.OpenRead(fileName); XLS.ExcelUtils.ThrowNotSavedOnDestroy = false; fileStream.Seek(0, SeekOrigin.Begin); XLS.IWorkbook excelBook = XLS.ExcelUtils.Open(fileStream); //error Any help would be appreciated thanks. My xls file is attached. I don''t have this problem with all excel files, I''m trying to figure out what''s special about this one.

Hi Brian, I am afraid we would not be able to add support for opening this file since its not a BIFF8 file. Essential XlsIO can only read an write BIFF8 files but this file is a BIFF2.1 file. You should be able to open the same file if you resave it using MS Excel into BIFF8 format. Sorry for the confusion.
