The suggestion of copying the directory "crystalreportviewers13" into the project directory is a good one, but...
If you are running the report as localhost, you should not need to do this as localhost assumes default app pool and CR is configure to use that out of the box. Typically the moving of the viewer directory is needed when you deploy the app and install it under a custom app pool (the CR runtime has no idea about app pools so it will not configure the viewer for you). See if you can follow the steps in this blog:
