I had the same problem. The first line of the exception message is indicating that your project is looking for Version = 12.0.2000.0.

Whenever I attempted to rebuild, messages in the Output window of Visual Studio (2015) indicated the same problem and prompted me to look at the preview.aspx file (C:\Windows\Microsoft.NET\Framework\v4.6.81\ASP.NETClientFiles\crystalreportviewers13\preview.aspx).

In my case, I simply changed the references from 12.0.2000.0 to 13.0.2000.0 (the version in the GAC).

Problem Solved.

Hope that helps!
