I had the same problem a few days ago, and I solved altering a piece of code in 
the  Office\Excel\SpreadSheet\Workbook.cs

     public static Workbook Load(string file)
        {
                        // I Changed the following piece of code because of error "stream not writable"
            //return Load(File.OpenRead(file));
            return Load(File.Open(file, FileMode.OpenOrCreate));
        }
