Are you sure you have Excel installed?
If so, here is the code I use to startup excel, use xlswrite1(), and
shutdown Excel:

			%----- Open Excel for writing.
			Excel = actxserver('Excel.Application');
			if ~exist(excelFileName, 'file')
				ExcelWorkbook = Excel.workbooks.Add;
				ExcelWorkbook.SaveAs(excelFileName, 1);
				ExcelWorkbook.Close(false);
			end
			Excel.Visible = true;	% Make Excel visible.
			% Open up workbook.
			invoke(Excel.Workbooks, 'Open', excelFileName);
			% Save the reference to this workbook so that we can later activate
it, in case we open multiple workbooks.
			%wbNumber1 = Excel.ActiveWorkbook;

			% Do the actual writing of the data to the open worksheet.
			xlswrite1(excelFileName, dataArray, 'MySheetname', 'C3');

			invoke(Excel.ActiveWorkbook,'Save'); % Save to disk.

			% Shut down Excel.
			Excel.Quit
			Excel.delete
			clear Excel;  % Remove variable from workspace.
Good luck,
ImageAnalyst
