Projects that target the .NET Framework 4 or the .NET Framework 4.5 also reference the following assemblies. These assemblies are not part of the Visual Studio Tools for Office runtime redistributable. Instead, they are dependent assemblies that must be deployed with your solution. By default, they are copied to the build output folder for your project (the Copy Local property for these assemblies are set to True). If you deploy your project by using ClickOnce, these assemblies are included in the generated package.

Microsoft.Office.Tools.Common.v4.0.Utilities.dll Provides the base classes for the generated ThisAddIn class in VSTO Add-In projects and the generated Ribbon class in all projects.
If I use only ver 64, it fails to find file Microsoft.Office.Tools.Common.v4.0.Utilities.dll
There is a file, but with no “Common name”
