Hi Sachin Saki,

There is no Excel runtime version. You need to install the full Excel
application on the server.

Users could run your .aspx page and use the Excel viewer to see the finished
workbook. But the Excel viewer cannot be used to add data to a workbook.

I am facing the problem with excel. here is my question and what i m doing
?

At server side: When users comes to the .aspx page, he gets the option of
downloading a excel file. when he clicks on download, (one blank template
is
already exist at server) excel file is created and populated with data
from
database using VBA and Macros are written for this and working fine. I am
referencing a Interop.Excel dll which maps to excel.exe when excel is
created
at server side because i m creating excel.application, workbook, sheet
objects which require excel must be installed on server.

But Client do not want to install complete excel. He wants to install only
"Run Time version of excel". Please let me know that whether run-time
version
is sufficient for above functionalitly or not. or Do we require to install
complete excel setup on server.
