Closed Issue: Reading Protected Excel file throws exception [2040]

Hi,
Our users will upload a protected excel (workbook and sheet) which we convert into stream and pass it to excel data reader.
I've got the below exception from ExcelDataReader.cs (Line : 139)
"No data is available for encoding 6236."
 
Pls let me know if there is any fix for reading protected excel.
 
Thanks
