CoolUtils TotalPDFPrinterX causes ASP C# site to crash
<p>My company has purchased the CoolUtils TotalPDFPrinterX from <a href="https://www.coolutils.com/TotalPDFPrinterX" rel="nofollow noreferrer">https://www.coolutils.com/TotalPDFPrinterX</a></p>

<p>I make an HTTP PUT from Postman to the API and I get “Could not get any response”.</p>

<p>When running on my Windows machine the PDF prints fine however on the server the site crashes and in the event log I get the error "A process serving application pool '[MY_APP_POOL]' failed to respond to a ping. The process id was '[MY_PROCESS_ID]'."</p>

<p><a href="https://i.stack.imgur.com/VLJC6.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VLJC6.jpg" alt="A process serving application pool &#39;[MY_APP_POOL]&#39; failed to respond to a ping"></a></p>

<p>Here is my C# code:</p>

<pre><code>PDFPrinterX ppx = new PDFPrinterX();
ppx.Print(fileName, printerName, "-ap Default");
if (ppx.ErrorMessage != null)
{
    WriteToSQL(id, false, ppx.ErrorMessage, 2);
    Console.WriteLine(ppx.ErrorMessage);
}
</code></pre>

<p>By writing to the event log I know the site crashes on this line: <code>PDFPrinterX ppx = new PDFPrinterX();</code> I have also surrounded the above code with a try catch and no exception is thrown.  The site still crashes.</p>

<p>Things I have tried:</p>

<ul>
<li>Uninstalling and Reinstalling the CoolUtils software</li>
<li>Giving EVERYONE Full control to the site folder and the CoolUtils program folder</li>
<li>Creating a C# desktop application using the same code.  THIS WORKS FINE ON THE SERVER.  It's just the ASP site that crashes.</li>
</ul>

<p>Does anyone know what might be causing this?</p>
