Microsoft Office is not installed on the computer
Visual Studio can't find the Microsoft Office application that corresponds to the project type. If you're developing a VSTO Add-in project, it means that you can't debug or run the project. If you're trying to create a document-level project, this message means that you can't create the project.
To correct the error
- Install the Microsoft Office application associated with the project type, including the primary interop assemblies. For more information about supported versions of Microsoft Office, see Configure a computer to develop Office solutions.
