Select the 'Microsoft.Office.Interop.Excel' reference -> right click -> properties -> set 'Embel Interop Types' to False -> set 'Copy Local' to True.
In my project. I just copy the 'Microsoft.Office.Interop.Excel.dll' to my local libraries.
The "'office, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies" exception was caught when I run my App.

Copy the 'Office.dll' to libraries again. and then
Select the 'Office' reference -> right click -> properties -> set 'Embel Interop Types' to False -> set 'Copy Local' to True.
Done.
