Please provide the following details so we can investigate the issue:

  • Sample conversion code
  • The file causing the problem
  • .NET Framework version used in the application where the issue occurs
  • Operating System details
  • Full path to the source file (ensure the application has the necessary permissions to access this path)
3

AsposeTest.docx (2.0 KB)

CHARTTST.XLS.DOCX (18.5 KB)

  • .NET Framework version used in the application where the issue occurs
    .Net 4.6.2, 4.7.2
  • Operating System details
    Windows Server 2022
  • Full path to the source file (ensure the application has the necessary permissions to access this path)
    Not sure what is being asked here.

The AsposeTest is the C# code and the XLS is the test file.

@tunedout

We could not reproduce this issue at our end. Could you please share the sample application and a screencast showing the issue?

6

You would like the application, which I attached in source in the Aspose.docx, since I could not upload a C# file and a screen capture of an exception?

7

@tunedout

We just not need the code file but a sample console application using that issue could be reproduced. You can compress the console application to a ZIP format and upload here or to some cloud storage and share it’s link here.

Screencast of steps showing the issue/exception.

8

The issue is when running as a Windows service, the error is created.

Test file needs to be c:\testfiles\test.xls

@tunedout

Please take a look at this image.png (6.4 KB). We’re currently unable to test this specific scenario on our end. Kindly allow us some time to create a test Windows Service application to reproduce the issue.

10

Yes it needs your GroupDocs.Conversion.dll, I assumed I would not need to provide that DLL

11

@tunedout

We’ll notify you as soon as we have more updates on this scenario.

12

Do you have any updates?

13

@tunedout

We’re still investigating CONVERSIONNET-7784.

@tunedout

We’ve pinpointed the issue: the exception is caused by the default font directories set in ConverterSettings.

As a temporary workaround, you can use the following code snippet:

var converterSettings = new ConverterSettings
{
    Listener = this,
};
converterSettings.FontDirectories.Clear();


using (var converter = new GroupDocs.Conversion.Converter(
    () => inputStream, 
    (LoadContext _) => loadOptions, 
    () => converterSettings))
{
....
}

The key code is this:

converterSettings.FontDirectories.Clear();

In v25.7, this will be fixed permanently. We’ll let you know as release is available for download.
