Hi,
We are not able to reproduce this problem. You can check your Windows event viewer and see if you see any error there. It is also possible that you have an AntiVirus program on your server that incorrectly kills our child process.
If none of those is the problem, we can take a look of your system to see what we can find if you can make it access to us.
Thanks!

Hi,
I tried looking the Event Viewer, but could not find anything from EO.PDF / EssentialObjects.
Nothing about a terminated process either.
Does the error Conversion failed. Failed to initialize conversion (1) mean that a process EO.PDF created, was terminated?
It it possible to change / configure EO.PDF to log more? Set a location for a .log file or something?
Could it be permission related? If so, where does EO.PDF create the process?
Unfortunately, I cannot give you direct access to the server.

Hi,
Yes. That error message means a child process was created but was immediately terminated (or crashed). The log usually does not help in this case since if our process is killed then it would have no ability/chance to write any log at all.
We tested it here on Windows 2003 R2 and it works fine. So you may want to test it on a different system and see if it works there. If it does work, then you can try to find the difference, and if it does not, then maybe you can arrange to give us access to that test system instead of your production system. Obviously we are not interested in anything on our production system, but usually in order for us to troubleshoot an issue we have to see it first. That's why it would be very helpful if you can give us remote access to any system that demonstrates the problem.
Thanks!

Hi, Like I mentioned, it works fine locally on my development machine running Windows 10. However, it fails on the production server running Windows 2003 R2 for some reason. There is no antivirus software on the server. I tried adding the following:
Code: C#
EO.Pdf.Runtime.TempFilePath = @"C:\Path-Where-IIS-Can-Write-Files";
EO.Base.Runtime.LogFileName = @"C:\Path-Where-IIS-Can-Write-Files\test.txt";
But nothing get written to the file or folder (that I can see through the FTP). Am I missing something? Where does EO.Pdf create the process? My test code that fails
Code: C#
EO.Pdf.Runtime.AddLicense("*key*");
EO.Pdf.Runtime.TempFilePath = @"C:\Path-Where-IIS-Can-Write-Files";
EO.Base.Runtime.LogFileName = @"C:\Path-Where-IIS-Can-Write-Files\test.txt";
EO.Pdf.HtmlToPdf.Options.JpegQualityLevel = 100;
EO.Pdf.HtmlToPdf.Options.PageSize = EO.Pdf.PdfPageSizes.A4;
EO.Pdf.HtmlToPdf.Options.OutputArea = new RectangleF(0f, 0.5f, EO.Pdf.HtmlToPdf.Options.PageSize.Width, EO.Pdf.HtmlToPdf.Options.PageSize.Height - 1.0f);
EO.Pdf.HtmlToPdf.Options.AutoFitX = EO.Pdf.HtmlToPdfAutoFitMode.ScaleToFit;
using (var ms = new MemoryStream())
{
EO.Pdf.HtmlToPdf.ConvertHtml("<html><head></head><body><h1>Hello!</h1><p>World.</p></body></html>", ms);
ms.Position = 0;
Response.ClearHeaders();
Response.ClearContent();
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=\"PdfTest.pdf\"");
ms.WriteTo(Response.OutputStream);
Context.ApplicationInstance.CompleteRequest();
}

Hi,
I do not have anything else to tell you. ConvertHtml will create child process through and run the actual conversion inside that process. If that process is killed by something or crashed, then you will receive this error. We have no way of telling you why this happens -- for example you might have some program on your server that just kills any "unknown" process. You will need to find that part out --- or if you can, you can give us access to the server and we will try to find it out for you. But there is no way for us to tell you what's happening without seeing the problem at all.
Thanks

I cannot give you access to the server due to security reason. But I can give you the URL to the test page which fails for me.
There is no debug version you can provide me with? Which logs and reports a lot more?

Hi,
There is really nothing else we can do unless we can have access to the machine --- and even that we can't even guarantee that we will be able to find out the root cause if it is something abnormal particular to that machine, all we can say is we will be happy to try. We have already told you logs won't help when the process is killed ---- it doesn't have any chance to write any logs.
Thanks
