Hello.
I am getting this error:
"Exception Details: System.Runtime.InteropServices.COMException: Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."
At this line:
Excel.Application xlApp = new Excel.Application();
I am using Visual Studio 2010 on SBS 2008 server.
I do not have Microsoft Excel installed on this SBS 2008 server.
Excel is installed on client computers.
This program is for a Web Application inside SharePoint 2010 that I want perform Excel tasks on the client-side.
Any suggestions on how to correct this error?
Thanks for your help.
