If you have some Error like

Exception from HRESULT: 0x800A03EC
Do Following Steps

  7. Stop the service automating Excel if it is running.
  8. Go to "Start" -> "Run" and enter "dcomcnfg"
  9. This will bring up the component services window, expand out "Console Root" -> "Computers" -> "DCOM Config"
10.  Find "Microsoft Excel Application" in the list of components.
11.  Right click on the entry and select "Properties"
12.  Go to the "Identity" tab on the properties dialog.
13.   Select "The interactive user."
14.  Click the "OK" button.
