Hi Gianluca,

I Built the demo source code but by just registering the output dll and replacing original one the data streaming stopped in excel sheet.
Dll registration:
- I tried differnt methods like -regasm and regsvr32 tools for both x64 and x86 versions more over I performed configs. to register the
Dll after every successfull build and the same result

the client application subscribes to the same Items and data is pulled successfully from light streamer which works really with many real custmoers.

best wishes,
Programmer
