NReco.PdfGenerator The pipe has been ended error on the server

Question

I'm using NReco.PdfGenerator for my PDF documents(that component is based on WkHtmlToPdf tool), my code allow me to create a pdf calling a function with the parameters controller, action, model:

public static byte[] GeneratePdfDocument(System.Web.Mvc.Controller controller, string viewName, object model)
{
     string result;
     controller.ViewData.Model = model;
     using (StringWriter sw = new StringWriter())
     {
         ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
         ViewContext viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
         viewResult.View.Render(viewContext, sw);

         result = sw.ToString();
     }

     return (new NReco.PdfGenerator.HtmlToPdfConverter()).GeneratePdf(result);
}

With this code I can create a PDF easily from my views and it's working great on my development environment but on a server I'm getting this error:

The pipe has been ended.

I think that is maybe a problem with permissions or some configuration on my IIS, any idea?

You are probably missing Visual C++ Redistributable Packages for VS2013 (x86). Even if your server is running 64bit Windows, you need to install the x86 C++ Packages.
