I solved using open windows explorer->Tools->Folder Option-> select "File Types" tab -> click on "New" button and Click on "Advanced" button provide the extension and choose Microsoft Office excel application ->OK(twice)

That's it.

Use Fiddler or the IE developer tools to examine the Content-Type header of the HTTP response. It should be: `Content-Type: application/vnd.ms-excel' (see here).

Also, look for a header like Content-Disposition: attachment; filename=foo.xls. If no such header is present, consider adding one.
