I get the following exception (no actual message, just a stack trace) when trying to generate some PDF with Rotativa, in an ASP.NET MVC application.
System.Exception at Rotativa.WkhtmltopdfDriver.Convert(String wkhtmltopdfPath, String switches, String html) at Rotativa.WkhtmltopdfDriver.ConvertHtml(String wkhtmltopdfPath, String switches, String html) at Rotativa.ViewAsPdf.CallTheDriver(ControllerContext context) at Rotativa.AsPdfResultBase.BuildPdf(ControllerContext context) at Rotativa.AsPdfResultBase.ExecuteResult(ControllerContext context)

The issue is not related to missing C++ Redistributable Package for Visual Studio 2013(MSVCP120.dll), as they are installed on the machine. Actually, some PDF can be generated through the application, which makes me think there is something in the view that causes Wkhtmltopdf to stop working sometimes...
Any idea as to what causes this exception or how I could debug it?
(The Rotativa version is 1.6.4 I am using MVC5)
I found the solution after a number of trials and errors. This question also pointed me in the right direction. It is apparently an issue with wkhtmltopdf page breaking algorithm, and large table or HTML blocks. So, to solve my problem I changed my HTML into smaller chunks and it now works.
