The conversion provider cann't be found.

[daniel.dority]

I've reviewed the other threads but I cannot seem to get this working. It is currently failing in PRODUCTION.

Code: Select all

[InvalidOperationException: The conversion provider cann't be found.
Please make sure:
1. the folder "plugins" under the same folder of Spire.Pdf.dll
2. exists "plugins\HTMLConverter.dll" and other "plugins\*.dll"]
   Spire.Pdf.HtmlConverter.Qt.HtmlConverter.init(String url, Boolean enableJavaScript, Int32 timeout, SizeF pageSize, PdfMargins margins) +237
   Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert(String url, String fileName, Boolean enableJavaScript, Int32 timeout, SizeF pageSize, PdfMargins margins) +64
   Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert(String url, String fileName, Boolean enableJavaScript, Int32 timeout, SizeF pageSize, PdfMargins margins, LoadHtmlType urlHtml) +42


1. We are fully licensed.
2. Redistributables are installed.
3. Plugin folder is in the bin folder.
4. Permissions are applied to the application pool account.
5. Application pool allows 32 bit applications.
6. License file is in the correct spot.
7. We tried the plugin path directly with on success: Spire.Pdf.HtmlConverter.Qt.HtmlConverter.PluginPath

Windows Server 2019 Standard
64 Bit
Version: 10.0.17763

Application is deployed through DevOps using web deploy IIS imports.

Any help is greatly appreciated.

Thanks,

Hello,

Thank you for your inquiry.
In order to help us investigate your problem accurately, please provide the following information. Thanks in advance for your assistance.
1. Your application info (E.g. Asp.Net Core, X64 platform)
2. Which plugin do you use? the x86 or the x64?
3. Does this problem also occur when running on local?

Sincerely,
Annika

1. Any CPU
2. How do I tell? I believe its the 86x one because I had to set Allow 32 bit applications on the old server.
3. No.

Hello,

Thank you for your sharing.
We did an initial test but did not reproduce your problem on my side. I speculated that it should be caused by a mismatch between your project platform and the plugin version. You could use the following code to choose the corresponding plugin. ​If the problem still exists, please provide your project (which can reproduce your problem) for further investigation. You could upload it to the DropBox or OneDrive and then share the download link with us. Thanks in advance.

Code: Select all

string pluginPath;
if (Environment.Is64BitProcess)
{
    pluginPath = @"D:\Spire\plugins-windows-x64\plugins";
}
else
{
    pluginPath = @"D:\Spire\plugins-windows-x86\plugins";
}
Spire.Pdf.HtmlConverter.Qt.HtmlConverter.PluginPath = pluginPath;

I'm getting frustrated with the one response a day support.

What are you hours so I can catch you throughout the day. I am on CST.

After downloading the new bits and targeting x86 platform it can now find the folder.


This line of code is now not generating a single thing. It is taking our HTML content and producing a 0 KB file.
Spire.Pdf.HtmlConverter.Qt.HtmlConverter.Convert(content, placeholder, true, 20000, new System.Drawing.SizeF(612, 792), new Spire.Pdf.Graphics.PdfMargins(0), LoadHtmlType.SourceCode);

I can guarantee that the content has HTML in it. And the placeholder contains a temp file.

What can I do next?

We have abandoned this product in favor of a competitor. We can continue the conversion in our email thread if you have any questions as to why.

I had the same problem as described here.

I resolved it by doing the following:

Under Build settings->Platform Target, we have Any CPU

Uncheck "Prefer 32-bit".

This resolved the issue for us. However, I would like to know why?

Thank you,
Tom

Hello,

Thanks for your inquiry.
For different Platform targets, you need to use the corresponding version of QT plugin. In your case, you may be using the X64 version of the QT plugin, so there will throw exception when “Prefer-32bit” is selected as the project Platform target. For the different Platform targets, our website provides the download link of the corresponding version Of QT plugin(as shown in the screenshot below), you can access the download page from the link below.
