Failed to add link "Microsoft.ReportViewer.WinForm" v11 to VS2012 project

I was prompted to migrate a WinForm application developed in Visual Studio 2008 to Visual Studio 2012. One of the win forms contains a Report Viewer component which is taking longer than I expected due to the Microsoft.ReportViewer.WinForm dll reference which I am not I can import into the project.

These are the steps I took:

• Transferring the application, made minor adjustments.
• Reconstruction of the project, some errors appear in the Error List panel, most of them have already been cleaned up.
• The remaining errors are related to SSRS and Report Viewer.
• An error in the import statement Importing Microsoft.Reporting.WinForms "indicates that the link is not loaded into the project.
• Right Click Project -> Add Reference ... -> Build -> Extensions -> select Microsoft.ReportViewer.WinForms and click OK.

• Saved project, then solution and closed Visual Studio.
• Open the solution again. Not only do errors persist, but the link I selected in the Assemblies list appears as unchecked .
• Double check the dll file exists at "C: \ Program Files (x86) \ Microsoft Visual Studio 11.0 \ ReportViewer". The file is there, and the version is correct.

Does anyone understand what's going on here? Suggestions and comments are welcome.

Thanks in advance.
