There are EXCEL spreadsheets present on this system.Also one can open, edit and save EXCEL sheets. But when I check the presence ExcelServer on the C:/ Program files...only 0 kb files are there under MS office(11)/ Excel. Som can 0 kb files deal be ok for an Working Excel sheets?

Only EXCEL folder is there in the MS office.(0 kb/MS word etc are missing). When I do a global search for EXCEL, there were Excel11.pip( 11 kb ),but no EXCEL server.

Answer 1

Using the registry?

[EDIT]

by checking the presence of the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office in the windows registry

Answer 2

There's no such thing as Excel Server, AFAIK. The Excel application, however, can be tested for by trying to create the COM object ExcelApplication. A quick search of either SO or Google should find you some code for whatever language you're working with - a typical means of doing so is by using CreateCOMObject().

Answer 3

You could use Microsoft.Office.Interop.Excel, and try to obtain an instance of Excel like var excel = new Microsoft.Office.Interop.Excel.Application().
