Cannot find wrapper assembly for type library "Microsoft.Office.Core"

Missing this reference "Office = Microsoft.Office.Core"?

Here is how you can add the particular reference:

Step 1: Right-click your project

Step 2: Select "Add reference.."

Step 3: Click on the "COM" tab

Step 4: Scroll down to select "Microsoft Office 12.0 Object Library".

I followed the instruction from the link below and the problem is resolved. The problem is related to a Windows update, so after I remove the reference Microsoft.Office.Core and rebuild the project, the problem is resolved.

Warning: The referenced component 'Microsoft.Office.Core' could not be found
