NReco PDFGenerator issue

Question

I've been using this tool for about a week, and now, today, it just stopped working. I've reverted the rest of my code back to the previous state and I keep getting the same error.

All that I'm getting from the Exception that is thrown is:

An exception of type 'System.Exception' occurred in NReco.PdfGenerator.dll but was not handled in user code

Additional information: Cannot generate PDF: (exit code: -1073740791)

From the Windows Event Log:

Faulting application name: wkhtmltopdf.exe, version: 0.12.2.1, time stamp: 0x54bd0265

Any ideas what could be causing this?

Answer 1

The reason of this error is not in your code: it seems something changed in your environment and wkhtmltopdf.exe stops working because of missed VC++ 2013 runtime libraries (required for latest v.0.12.2.1).

You can download and install them from Windows Downloads: Visual C++ Redistributable Packages for Visual Studio 2013

PdfGenerator embeds x86 build of wkhtmltopdf and you may install only x86-version of redistributable package ( vcredist_x86.exe ).

--- update ---

For latest wkhtmltopdf 0.12.4 VC++ 2015 runtime libs are needed.
