Why Do I See the Error Message of Compile Error in Hidden Module?

Now Office 2016 is upgraded from a 32-bit version to a 64-bit version. The Compile error in hidden module error message usually appears when there are dome 32-bit add-ins versions of the office in your computer, and they are incompatible with the 64-bit version.
