Dear Mone,

sorry for Delayed response

kindly be informed that:-
- I downloaded and installed the Demo
- I tried to just run the demo as is on your server , I followed the instructions and compiled the project successfully then I replaced the DLL file allocated in installation directory e.g (C:\Program Files (x86)\Lightstreamer .NET RTD Server Demo library for Excel\lib\RTDLibraryExcelDemo.dll) with the new compliled dll produced from Demo Source code.

- when I opened 'ExcelDemo.xls' or 'ExcelDemo.xlsx' Sheets associated with the Demo there are no data displayed or updated
please find attached picture for details
- Are there any configuration to do in Excel??
- How to make sure the rtd server is registered successfully from excel?
- Is there a way to debug the RTDLibraryExcelDemo source code while opening excel?
